This is so interesting when you're not "forced" to learn it
where were you forced to learn how microwaves work?
Physics lecture :(
It seems like you use to hate your studies
Not just this.Whenever we are forced to learn anything, it seems bitter but when we are eager to learn anything it seems sweetest thing in the world.
very true bro
It's kinda unbelievable that friction exists at a molecular level. Really, interesting way of explaining. Thanks for that.
Remember this is interesting. The explanation is wrong, misleading and self contradictory.
ofcourse there is friction, in 10th standard we studied about nano technology, do you remember it has so much friction at nano level that's why we can't use it so much
@@chuanglu9162 will you plzz elaborate?
@@satechknowledge2303 are abdul tum puncture banao
@@satechknowledge2303 what he meant was the explanation is self frictioning and produced alot of friction.
Fun fact, it was not a chocolate bar that melted in his pocket, it was actually a nut bar. Whereas chocolate often melts in your pocket anyway, nut bars don’t - that’s how he realised that something weird was going on
It doesn't surprise me that they use misinformation like that right out of the gate.
@@eriklarson4082 the way you said it makes it sound like they did it on purpose. Seeing as this may be a more common misconception, it's not unforgivable so long as they get the science part right, if they were focusing on history instead of science then it would be less forgivable.
@@eriklarson4082 bruh conspiracy against nut bars obviously.
This pleases the nut
That’s nuts!
Thank you for not having cheesy background music in the video. It can be such a distraction. Loved the video!
This video explains exactly why I prefer my older microwave. Instead of a rotating plate and a stationary waveguide on the side, mine has a stationary plate and a spinning waveguide above the food chamber, spun by air from the exhaust fan. It distributes microwaves more evenly. Much simpler and far more efficient, and less parts that can break or wear out.
It's why I like my commercial microwave which has two magnetrons and two stirrers and cooks faster and more evenly than any home unit. 2100 watts of microwave energy.
@@jameschristiansson3137sounds amazing! What's the brand and model?
@@Carolina-mw4po We have the Amana HDC212 at our small business. Other brands with this level power include Sharp, Panasonic, Midea Equipment, and Solwave. Some caveats: these are sold for commercial usage. Depending on the manufacturer the warranty will not be honored for home usage. These microwaves require a 240V outlet dedicated to just the microwave. With that said, if you decided to go this route the price may be better from a restaurant supply company rather than someplace like Amazon. Shop around.
You should have explained the Mesh on the window.
It is specifically designed so the electromagnetic wave can't get out.
It does that, by having holes of a small enough size.
(I believe smaller than 1/4 of the wavelength or something like that)
Yes, I was waiting for that as well and was surprised that it wasn't talked about since it is a very important component in protecting you from radiation.
Faraday cage right?
Thanks a lot
Jesus is the Son of God. Believe in his death and resurrection then confess his lordship over your life. Love yall🙏♥️
Yup and also the mesh is connected to Earth
Too easy. At that wavelength the microwave is over decimeter in size, while mesh is like sub-millimeter.
This is how things should be taught! One of the best, most informative, easy-to-understand videos I have ever seen.
Schools should move away from text books and use mostly videos.

My GE microwave from 2005 finally crapped out. At first ua-cam.com/users/postUgkxO_Bc204MGjxDl87cOKcdgaRhzSqGmv_g I was unsure because I was looking for something with the exact same features. Found it with this one. Interior space cavity was large, but the outside was smaller than my old one. I love the one-button push for 1-6 minutes, and the 30 second add or 30 second start. and MOST IMPORTANTLY, I love how you can adjust the power level during cooking. The reviews said it could not be done, but this marked all the other boxes. and happy to say, it does. I can hit 1 minute start, and change the power level from 10 to 5, 30 seconds in, without interruption. my favorite feature!
I was heating hotdogs in the microwave a while back, and the first time they came out still cold (this one doesn't have a rotating plate). I put them back in, but this time rotating the plate 90°. Left them in for the same amount of time, and bam. Steaming hot. I was so baffled about this ever since. Now I know it had to do with hot spots from the micro waves. Thank you.
You shouldnt be heating anything in microwave, just throw it in the bin. Anything you put in there will taste like shit, absolutely unhealthy. Milk taste literally plastic after heating in microwave 🤢

Don't mind if I do
My older microwave malfunctioned once and didn't turn off when I opened the door. My hand closest the microwave felt like the hair was standing up. Didn't hurt or anything. I turned it off after a couple seconds I realized what was happening. Years later they had to cut off my hand due to massive deformities. Kidding.. nothing happened.
😂😜
LMFAO 😂 your name is the cherry on top of this comment 🤣
Lmao the same thing happened to me the other day and that second-to-last sentence got my heart rate up. Ooooh, the jokes 😂
Look at my face! My mom peeled of the protective film on the glass door of the microwave when I was a baby. She would warm up my milk every day in it, with me in her arm. Yes. My face was right in front of it. By 9 years old my face started to deform. My profile picture was taken in 2015. No joking here.
@@Elaba_ Just my face. If you look close, you'll notice how bad
Me suspecting that chocolate with water molecules started to melt
But the man with 70% water
You got the point lollllololololool
Well I guess chocolate melts much faster than man.
@@Chirag.D da fuq kind of bs is this? 🤣
@@Chirag.D complex proteins and skins ?? What is that supposed to mean ? First of all, the chocolate didn't get cooked it just melted. Humans have a large surface area and higher heat capacity so I think that is why the scientist didn't feel any effects as the heat dissipated quickly. If you have a powerful machine it can and will literally cook you from inside out if you come in the way of the fields.
Hi might have felt his skin getting warm, but not thought anything of it.
The actual answer is we have heat sensory nerve endings in skin mainly, and skin doesnot have much water. So it didn't heat up, and he didn't feel the heat.
Water is mainly in blood and internal organs, which don't have heat sensing nerve endings. So even if his organs get cooked, it would take very long for him to realise that
I can’t believe it took me so long to find this channel. This is an awesome animation and explanation. Thank you!!!
one more thing to add ..
The frequency of the microwave is close to the natural frequency of water which leads to resonance ..
it is not the same as the natural frequency of water because in this case the surface of food would burn quickly before the inside getting cooked ..
please correct me if there's any mistake..
Good video. You should've covered the wavelength size of the 2.45 ghz vs cell size of the metal seethrough mesh of the front door, that would be a good explanation why microwaves cannot penetrate that mesh. Maybe even cover induced harmonics in it too just for fun.
YES that is exactly what I asked but now you've explained it so I understand LOL
2.4ghz is actually the wavelength of Wi-Fi routers and 4g cellphones. Interestingly cell phone radiation is considered a possible carcinogen by the national cancer institute and a lot of scientific studies have been conducted to confirm this. Not sure about microwaves but I dont like the idea of having one right next to my head like the ones they started putting above the stove.
@@archive8080 "a lot of scientific studies have been conducted to confirm this" -- that's a convenient way of saying "I don't actually read, but if I do read, I don't actually comprehend what I've read".
From your very own source of National Cancer Institute:
"In 2002, the International Agency for Research on Cancer (IARC), a component of the World Health Organization, appointed an expert Working Group to review all available evidence on static and extremely low frequency electric and magnetic fields (12). The Working Group classified ELF-EMFs as “possibly carcinogenic to humans,” based on limited evidence from human studies in relation to childhood leukemia. Static electric and magnetic fields and extremely low frequency electric fields were determined “not classifiable as to their carcinogenicity to humans”.
@@acmilanshevachels that's what I said, possibly carcinogenic. "I dont actually read", obviously you are projecting. If you want to challenge my claim, we can get into it. If not, take a step back and wait until you've seen the evidence before making judgements.
@@acmilanshevachels wow… do you think this is a toxic “politics” UA-cam channel??
I find that people who are as pompous as you, concerning engineering matters, are usually the ignorant ones.
I wish this person was my physic teacher back in high school, it would make life much more easier and less stressful to study my other 9 subjects at that time
The cooking from the inside part just isn't true. The strength of the wave inside the food is of function e^-x and the more inside you are the weaker it is. The inside gets heated by the little wave strength that is there and by the heat passing from the outside to the inside. Put anything relatively large in the microwave and cut it in half after heating it. You will see that its colder on the inside. That statement really killed the video for me...
Yeah, unfortunately it isn't entirely accurate. You still do get better heat penetration in most circumstances though.
yep specially if you want to heat thick liquid such as soup. I've tried various brands of microwave oven to heat cold soup, unfortunately none of them are effective at the moment.
That has everything to do with the microwave in question. Commercial ones use multiple magnetrons for even more efficiency.
There are some exceptions. For example a jam filled doughnut. In fact, because of the lack of H2O in the dried out bread and the abundance of H2O in the jam center, all the microwave energy goes towards heating the jam. It is in fact quite dangerously deceptive, as you'd take out the jam doughnut and it will feel a little warm, but as you bite into it you'll get a nasty surprise because the center will be extremely hot.
Also, as cardboard and plastic do not contain any H2O there is no effect of heating resonance from their molecular structures. This is easily demonstrated by heating pizza in a microwave while still in its cardboard box takeaway container. The cardboard is not hot, yet the pizza is.
@@RoySherfan This phenomenon is what makes Hot Pockets so hazardous.
Amazing! So, i could learn that a standing wave is concerned by 2 microwaves interfering on each other. A first microwave (incident) is created from an electric source and flows through the resonance cavity. When it finds a reflector, the first microwave reflects and creates a secondary microwave in opposite way. The phase of the secondary microwave is 180 degrees distant from the first one. Implies that at this moment one phase is canceling the other when the amplitude is maximum and minimum, one to the top and other to the bottom. But as the 2 waves is travelling, the distance between the phases isn't static, so when the 2 microwaves encounter at the moment of maximum amplitude for both of them, they interfere constructively, point of maximum energy. That's the reason that the standing microwave formed is applying more energy always at same points, cause the distance between phases is varying, but as it's originated of the same source, they have the same frequency, velocity and amplitude, the points of maximum amplitude of both of them will always be the same. Interesting that the encounter of no amplitude of them, don't create more energy at all. But as microwaves flows, that's the point that they encounter constructively. It was not common sense to me. Thanks!
What bothers me is that the cheese shows multiple hotspots. This is contrary to the picture of a single standing wave. If there is a single standing wave in the cooking (resonance) chamber, then we must have 2 or 3 or 4 hotspots aligned in a row spaced at equal distances. Right? But this is not shown in the "sea of cheese" plate..... I am confused.
@@TobyOnTube thas caused by the rotation of the plate, wich allows the hot spots to warm the cheese in other points
@@Mateus-gt2iq: Thank you, but I have to disagree. If you look closely then the experimenter places a square-shaped tray into the oven. It's impossible for it to rotate within the oven chamber given its size. I hope you agree on this. However, your answer could also be interpreted for the case where there is a fan rotating in the ceiling of the MW oven (randomly?) distributing / reflecting microwaves within the oven while the food is stationary. But also this can be argued against because if you look closely the model has the design where food is rotating (rotating mechanism at the bottom). So, if I am correct in my chain of arguments, then the food (cheese) is stationary, the generated microwaves must also be stationary (no reflecting fan in the ceiling). Hence my original question is still open..... Looking forward to your reply. :)
@@TobyOnTube I misunderstood you, you made a good point. I just realize that some microwaves has a rotating fan that spreeds the waves in other directions, i didn't know about that, thank's. The combination of the inclination of the fan blade and rotation, cause waves to travel a 3d shaped pattern. I tested by myself at home, my microwave just have the turntable, so waves is really stationary. Maybe some microwaves has turntable and rotation fan , makes sense to me
@@Mateus-gt2iq: Thank you for a constructive discussion. What I do not understand is that the hotspots melted into the sea of cheese are not arranged as expected: if there is a single standing wave with travel direction along the left-right axis of the oven, then I would expect 3 or 4 hotspots at equally spaced distances around the depth where the waveguide is located (at the upper right side). But this does not seem to be the case. Its kind of a pity from a didactics and educational point of view: In the 5 - 10 minutes before operating the microoven you imprinted a picture of a standing wave in the head of students, but then the hotspots are not where they are expected according to the standing wave picture...... I hope you understand my point.
You simplified it wonderfully

This and a video before regarding insulators were both so very amazing and great learning experiences, thank you and keep up the good work.
Things I learned from this that no even talked about in school or even university/college:
Reflected waves is 180° flip along Y axis of the wave that would have propagated if there was no reflector.
Heating using microwave is caused my friction due to oscillating water molecules.
The L=N*wavelength/2, it's application.
The standing wave application in a more easy to understand way.
And lastly it was in a fun and thought provoking manner.
Explained really well.
Highly appreciate the effort for making the video!!
Really Love the video, very informative, can imagine how much hardwork went into the animation and stuff, thanks guys for making a normal person more educated, specially in concepts that touch upon our daily lives. 😀😀
Skin depth concept is also used in this..
Never mind the melting chocolate bar in the scientist's hand, he should probably stop playing with microwaves and go directly to the emergency room based on what looks like 3rd degree burns!
Na, that is the chocolate melting
it´s a chocolate bar... not an metal bar... no need to have such amount of energy (heat) to melt down

Nice I was looking for it.
Interesting that the microwave oven was sort of praised at the end there. I always felt that the way my food came out of a microwave oven left something to be desired, and that it didn't stay hot long enough.
I stopped using microwave ovens almost ten years ago, and I don't miss them. I reheat all leftovers in my toaster oven or in my propane oven, and occasionally on my propane stovetop.
I find that it preserves the original quality of the meal. Usually I put the food in a casserole dish with some foil on top, at least to begin with.
Agree! I’ve never owned one. Everything came out of that thing limp and unevenly hot. It only takes a few minutes to heat things in a toaster oven or on top of the stove. Are we really that impatient?
I have not used a microwave for @ 12 years now. din't miss it either.

Well done! The microwaves are confined within the cavity due to the metallic mesh attached to the door glass . Without it, microwaves will escape.
They still escape. Check it yourself with a microwave freq reader. I did and have found them to escape. They could be picked up on the other side of my house.
@@Stefano-tb8ls Are you actually checking the electromagnetic waves? If so, many appliances do that.
@@Stefano-tb8ls Check your microwave freq reader with your microwave disconnected and you will still find 2.4~GHz
They definitely still escape. Whenever I use Bluetooth while the microwave is on it gets disrupted even when I am standing over 5 feet away. When the microwave turns off the Bluetooth goes back to normal. I think these microwave companies are lying to people to make them think it is safer than it is
Nice video, but i think it skips over the most important questions
* How does a magnetron work?
* How does a waveguide direct the waves in one direction
* How does the microwave chamber prevent any waves from coming out?
Fantastic explanation

Great video. Would've wished for some details on how the EM waves are confined inside the microwave to protect us from harm.
That would be fiction.
@@Living4YHWH but not really.
Since metal basically reflects the waves back, the inside of a microwave is built out of metal which doesn't let the waves pass through (as they reflect back in), same with the glass that most probably contains a thin layer of metal which does the same job. And so the waves never go outside of the microwave oven but remain inside throughout the duration. That is the reason why, when opening the door to the microwave oven while it is working shuts it off, it's a safety feature as to not allow the waves to go out of the microwave since the door isn't there to reflect it back anymore
@@Living4YHWH He was asking about the function of Faraday cages, not about the existence of your brain.
@@Nawmps 🤣hell yeah dude
One important thing to mention.. Never ever put a metal in a microwave oven. (my 6yrs old son asked me to write it)
Reason?
@@thehaseeb9136 Metal reflects the waves which can reflect back towards the magnetron and damage it causing sparks and a fire.
Forgetting about a foil lining in a wrapper has ruined a few sandwiches for me... Before you can even shut the microwave off it's too late, your food already tastes like burned metal...
another important thing to mention: never let a 6 years old near to that microwave oven (health hazard, EM radiation is damaging your tissues )
@@needsomehike when we open door of oven to take out food, will it harm us? My mom leave door open for some seconds after taking it out and microwave oven was off but light was on
This was explained really really well. I wish schools taught this was. I would definitely like physics.

Very nice explanation how microwave oven works. After hearing standing waves and integer multiples of wavelength straightaway remembered my quantum physics and electromagnetics University studies. Thank you!
Video: "Cook from the inside out"
Me: True, you can boil water even if it is inside a covered small ceramic container. And the ceramic wont became that hot, only the water will start to boil. But for a large chicken you need to adjust the wavelength a bit so it penetrates deeper and add a couple of watts to cook a whole chicken, but then you have it. Did not hear that detail in the commercial :-)

Amul: The taste and pride of India 🤩🤤🤤🤤
Indeed
Microwave cooked food dangerous, is it transform the food components into poisonous chemical
We all grew up watching Amul ad on TV and newspaper
@@Saveindian why do you think so?
There were way too many inaccuracies in this video. The most glaring one was cooking from the inside out. While it is true microwaves penetrate food, they are attenuated fairly rapidly and so do not make it to the very center of a mass of food item with any appreciable volume. Microwave ovens still rely on conduction to transfer heat from more outer regions of the food to more interior regions. That’s why the defrost program typically cycles the magnetron on and off. (Inverter based microwaves excepted which turn the power down thus allowing time to conduct heat to the interior in a similar fashion)
But how bro, I have read in books microwaves have larger wavelength than red light, infrared. Then it will easily penetrate into most food items.So heating should start in the reverse way u mentioned.
I am just saying my opinion (school student). Any reply is heartily welcomed.🙂
@@thepredator4711 check the Wikipedia page on microwave ovens. Without going into the physics of the what and how attenuation works, it penetrates food about 1-1.5 inches deep so anything thicker than 2-3 inches depending on the oven will end up with a cooler center.
@@andrewh2341 😃🇨🇳
Okay, that's only one, but you said above "There were too many inaccuracies". Either list all inaccuracies or better edit your comment.
Unrelated to video subject :- Microwave manufacturing companies know this fact, so that's why they sell only standardised sized microwaves to prohibit customers from putting very large food samples in microwave and uncover the lies of their market campaign by themselves. [DiowE]
Can you explain me there are how many inaccuracies except this one?
But one big question still remains, whether oven cooked food is safe for human consumption or not?
Oven cooked meals are safe provided the whole meals are heated perfectly, just like cooking meals on stove. You don’t want to eat raw chicken, do you?
@@smurfiennesSomeone considers cooked chicken is much more important than something can cause cancer
No. It destroys nutrients
Safe and not. Safe because it can kill germs. Non safe, because it produces acrylamide which causes cancer.
Its just heating. So should be no issue
Interesting. One thing I'd like to hear a more specific answer, than the statement 'don't worry about it', is how the radiatiom is contained w/in the unit.
Amazing explanation! Thanks!
"The electromagnetic radiation is always confined within it" - except when it's not. You can measure leakage and older microwaves leak more.
The leakage in older units is minimal, and typically around the door release lever, or if the door or seal is damaged. However, these tiny hotspots dissipate quickly with distance, so normal moving around a kitchen would result in only very low exposure.
Im still 12 i havent learn untill that hard. So i dont understand what you explain but im still intrested

jeeadv 22 aspirant sir i watch your videos in free time and they are damn interesting and explains science behind various instruments. besides marathon syllabus of jee adv your videos keeps me amazed in science. thanks a lot
Thank you for this nice explanation.
I worked over 25 years in restaurants industry . I have seen so many people place food inside microwaves for 5 minutes then not even one minute passes by they don't even wait for it to stop and they rip the door open exposing everybody to microwaves . That is how microwaves are dangerous . BUT if you wait for it to finish or switch it off then open the door it's perfectly safe.
Microwaves are not energetic enough to cause permanent damage. They will at best give you a burn (and even that only if you hold you hand inside for extended times; ie cook it) nothing more.
Both microwaves and Wi-Fi routers operate at a similar frequency, around 2.4 GHz. However, there are two key differences that prevent Wi-Fi from heating your food:
Power: Microwaves pack a much bigger punch. A typical microwave oven generates hundreds to thousands of watts (W) of power, while a Wi-Fi router emits mere fractions of a watt (mW). This immense difference in power allows microwaves to excite water molecules in your food, causing them to vibrate rapidly and generate heat. Wi-Fi signals simply don't have enough power to achieve this effect.
Focus: Microwaves concentrate their energy inwards, bouncing around the metal chamber until they are absorbed by your food. Wi-Fi routers, on the other hand, broadcast signals omnidirectionally, meaning they spread the signal out in all directions. This weaker, scattered signal isn't strong enough to heat anything in its path.
So, while they share a frequency band, the vastly different power levels and focus between microwaves and Wi-Fi routers mean you can safely use both without worrying about your Wi-Fi accidentally cooking dinner!
Reminds me of, “It's not a Bug, it's a Feature!”.
Microwave heating is not uniform, unless you're only heating pizza...
Not even pizza is heated uniformly
Newer microwaves come with this small fan installed on top to spead the waves some more idk if that actually works tho
Pizza is best re-heated in a toaster over or a pan.
Microwaving most food is kinda gross.
It's good for warming up food to cook in an oven or on the stove, but not by itself.
That's one major problem. Also when we need to heat large quantities gas stove is best.
meaning it time for you to get a brand new latest model. 🤣🤣🤣

I have a question. So, it told that the water molecules move and generate friction leading to heat generation. My question is - If we use an item without any water content in it, will it still get heated or not?
I don’t think there are any edible food items that do not contain water content
The "water" he said is the small molecules of water that probably doesn't even add up to a glass of water but they are still there. Just can't be seen with naked eye.
I had the exact same question! Did you figure it out?

Amazing video🎉
You haven't spoke about whether it is healthy to eat the food heated by a microwave
It is no more dangerous than eating food cooked in a convection oven. Perhaps even less so because convection ovens can burn food and that means free radicals. As long as there is adequate water in the food uWaves can't burn it because the water absorbs the energy.
I think it’s pretty obvious from the context of the video that there’s nothing to actually be concerned about.
thanks for clearing my understanding of microwave oven
Excellent
8:20 if this is true why if I measure electromagnetic radiation with a device that is designed to measure it spikes it up to hazardous level when the microwave oven is on and heating something, standing OUTSIDE and close of it, of the "confined area" , even without being used. Can you test this to corroborate what you said about the electromagnetic radiation being trapped inside the device and not leaving it?
'If you measure' ? Are you qualified ? And are you using calibrated gear correctly ? I doubt it. Microwave ovens are tested every new model for compiance. The narration @ 8:20 is correct
They still escape. Check it yourself with a microwave freq reader. I did and have found them to escape. They could be picked up on the other side of my house.
OSHA specifies new microwaves for sale in the US shall not emit more than 5mw/cm**2 (centimeter squared) at 2 inches from the appliance. So some energy can get out, but not enough to harm you.
Wasn't this channel called real engineering like couple hours ago!!.
They changed the name to this
Makes you wonder who's paying for their propaganda videos now.
thank to the one(gf i guess) who gave him Chocolate😁

This is the most educational episode of Moral Oral Ive seen
6:25 - Finally someone explained in detail how exactly a food microwave works.
So the greatest peaks of the microwave’s amplitude is the one that creates hotspots? It would make sense since all peaks in a wave has the most energy. What would happen if the peak of the microwave is below the food? As if the peak of the wave is actually greatest at the surface of the microwave oven’s floor and not on the surface of the food? Maybe the microwave oven is designed such that the peaks of the wave will always remain at the level of the surface of the food…
the standing wave pattern of a 1D system is simple,
the standing wave pattern of a 2D system is a mess,
the standing wave pattern of a 3D system is hell, it is next to impossible to "design" the cavity in any meaningful sense other than just make it and ok if there's no fatal flaw.
Awesome 👌 You simply made us understand each and every term of microwave... in very simple language.
Thank you ❤️
If nothing comes out, then why does my wifi in the kitchen go out when I turn the microwave on? my tv is 15 feet from the microwave and yet every time it interrupts the signal?
Something else going on. Hundreds of thousands of people don't have that problem.
Amazing learning animation method. Easy to understand
Such a great video I learnt microwave heating with full clarity .Thank you so much .
What kind of software you use to make this amazing animation. I also want to make some videos on some engineering concepts. So, please tell me Lesics.
He’s not gonna tell you because then you could get more views that him Lol
@@wirito they are focused on giving more knowledge to the students not making and competing for money 📈.
@@engineering_design I agree that their goal is to teach engineering but they also need income. They rely on subscribers and views to get money from ads. Less viewers less money.
They don't get less viewer if I make good video that will give more knowledge
@@engineering_design He's using Blender, he talks about it if I remember well on a video.
👍. It would also have been nice to explain the difference with radiation. Many people like my brother think it poisons their food making it radioactive 😅
@@jamesbenz3228 I've a scientific background so it's what I tried to tell him but he chose to believe in a conspiracy video of few minutes of someone random 🥴
Visible light is electromagnetic radiation. Does light poison your food? Radio and TV signals are electromagnetic radiation as well, do they poison your food? Not all electromagnetic radiation will make objects radioactive
Tell him to throw his phone away if doesn’t believe in safe scientific testing.
You can’t pick and choose which area of science you believe.
@@Zen_Power on the contrary, it's called being ignorant.
Ask him if he thinks there is Uranium in the microwave oven.
Who tf is cooking a turkey in their microwave
Mr Bean
only if the microwave is made in texas, its possible
Good sir, i ask you why not ?
Some are two in one
I think it was back in the 60's that... *everything* was cooked in the microwave. Whole cookbooks on recipes, just for cooking in the microwave. Yes, including turkeys.
I learned more about EMF here than I had in physics classes at school
It's still the same kind of BS propaganda you would have learned in school!
Seriously. Best explanation ever . Thank you!
how dous self balancing vehicle works like "solowheel,segwa, Ryno one weel bick" what is giroscope ? what is acclerometer? how the electronic process the feed back from the sencer and how the moter responces in detail with coding and electronic circuit design and details about processer and much more in simple language plz make it a long video 3d animaton even not required just a 2 D is enough
They use a gyroscope to and multiple sensors to get feed back of position and angle📐.
A gyroscope is a device that resist change in position as its always rotating. You can find better info if you watch a video about gyroscope!
Darn, how strong is her grip.
Great video! Maybe you could explain in another one the Faraday cage used to trap the microwaves.
Physicists and electrical engineers are rock stars in my book.
Yes we got complete understanding...
Thank you for the good explained video. Some things were unclear to me:
Does the microwave works only with water molecules or with any other fluid with polar molecules?
What is the effect of higher/lower frequency/wavelength on the transferred energy? Does it have a similar influence as the amplitude?
The higher the frequency the higher the energy
For a given frequency, ever material has a certain absorption strength. The wavelength of microwaves in microwave oven is specially matched to be absorbed well by water.
Fats and oils hest quickly in microwaves too.
each molecule has its own optimal wavelength (or frequency) but only molecules presenting a dipole can 'absorb' microwave. 2.45 gHz is not exactly the optimal for water but it is the closest authorized frequency. Other fluids such as ethanol (alcool) absorb more efficiently microwaves than water to convert it into heat. On the opposite, kerosene (a mixture of apolar molecules) is transparent to microwaves.
It is to be noted that the absorption efficiency also depends on temperature.
The answer to all your questions: Yes.
