Lol, it's Raman not Ramen, I guess I was hungry...

Now I'm hungry, too!

C.v Raman, a indian scientist...nobel prize winner...got this idea while on a boat
Girlfriend: We missed the sunset
Me: Dont worry I have milk and water at home
*Me* : Mom, I wanna see the sunset before we go
*Mom* : We have sunset at home already
*Sunset at home* :
This is one of the best 'why is the sky blue?' explanations I've ever seen. Connecting it with the fact that the sun appears yellow is a master stroke!
“Ramen scattering” sounds more like something I’d do when I’m broke and hungry
I think u might be jocking but just in case Raman Is the name of Indian Scientist "C.V. Raman" who discovered this effect. :D
@@ashutoshmahapatra537 Joking*
Ramen is a poor man's meal in America. A cup of noodles with hot water in other words.
@@thehotdogman9317 this is raman effect, not rAmEn effect
1:09 this is beautiful

This man makes us see physics through his eyes.👏🏻👏🏻👏🏻Great way of explaining.
that was simply awesome! I can't wait to show it to my daughter when she's old enough to understand the concept.
Show her now
Why not now?
You'd better show her now before those flattards get into her head first.
@@humanbeing1429 lol but true, very true!
Here is a more detailed explanation:
ua-cam.com/video/NafbGOQBlQs/v-deo.html
1:54 What you mentioned here is Raman effect(or scattering) after CV Raman an Indian physicist. He won the Nobel Prize in 1930 for this discovery.
Indians😑
There's also a rumor that the friend of the cousin of the nephew of the great great great great grandfather of Messi is Indian
where was YT when I was in the school? In the last couple of years I learned more on YT than during my whole education ;-)
Me too
Wow, you must either watch way too many youtube videos or you skipped a lot of school. 😁
I've tried the milk in water thing, and I don't remember it working that well. I need to try again. By the way, the scattering power of particles scales as their *(diameter^6)* so that's why the scattering works in just 1 foot of water, when it takes miles of atmosphere to work with small particles in/of the air.
You have to use very little milk
So we've learned today that the sky has milk😂😂
Mmmm... Milky air...
Hey sky, got milk?😂
I could oppose this comment but it's funny 🤣
@@axiomer47 🤣🤣
yummy cummy milk
Learned about those effects before but never noticed how simple this can be shown in action. Awesome
I am a physicist, and was trying to explain this to some friends (using words like quantum and Debroglie, yikes). It seems all I needed was milk and water :) Thanks for making such a simple demo with great explanations!
The sun is white and yellow at the same time? That’s a weird feeling for sure.
It's all the colours at the same time, which combines to form what we perceive as white
Quantum color 😂😂
Because the medium changes it. (Atmosphere contain water, oxygen, and whatever you call it)
That's why don't buy things through a medium. The price will become "yellow".
The Sun is the most racist thing ever, that's why.
The sun mostly appears white. It doesn't get yellowish until it gets low in the sky.
It is my First time that i have a FIRST VIEW to any YOU TUBE VIDEO and that too happened to be one of your Videos................Yayyyyyyyyyyyyyyyyyy !!!!!
I am a huge fan of "The Action Lab".......and i just love the different Experiments you do and the way you explain them..................Carry on doing EXPERIMENTS !!!!!
Gonna try this with the kids. They will love this. Thank you
The Action Lab, I love your videos and I watch them regularly. I gain knowledge from your videos and found it interesting too........
Inspired from you, I named my channel as 'The Crazy Lab'.
Wow, this is the best demonstration of why the sky is blue I have ever seen. Great work 👍🏼
This channel does not deserve 2.56M subscribers, It deserves at least 10 M subscribers
This is one of the best channels on UA-cam. Thank you for your very educational videos.
And as you go up in altitude you just see the blackness of space. That means the blue sky and the red/orange sunset is for our eyes down here in the atmosphere! Awesome design.
He kinda looks like Freddie Mercury with his mustache
Not really
finally, a decent explanation not just why the sky is blue, and also why the sun looks yellow
You should make laboratory manuals for schools with practicals like these. The ones schools give us, sucks ass.
Alot
They do teach this, read the books...
the blue scattering light, works for plants, we use blue lights in early plant life then red come flower ........... i love this channel it makes me feel smarterer
When you hear "Today I'm going to be showing you..." you know it's knowledge.
*K n o w l e d g e*
This is the best ever explanation about why is the sky blue.
I learnt more from this 4 min short video than from 2 (*) 40-mins lecture of Science in my class! Gr8 job!
Brilliant!!!! Bravo!!!!! Please educate all your children to a science rather than watching TV or cell phones TikTok!!
That's the best video you created in month. Actually.
If the sun looks yellow from our point of view inside earth's atmosphere, shouldn't the stars we see at night also be yellow since their light is going through the same atmosphere?
This is very easy to understand. I literally googling about why the sky is blue and why the sunset has reddish color, but i never understand. Lol. This is very informative. I'm glad you guys are able to help others who isn't good in science. Keep them coming
My long life question has been answered with demo. Thank You Very Much
I found this channel through King of Random. I really like how you show experiments and explain everything perfectly for others to understand.
Photons bless you sir, wonderful explanation! Thanks
Glass box, milk, flashlight, wall.
Rayleigh white-blue-orange, Raman white-black, and a quick easy 4th-power math. In less than 4 minutes.
No hype, no bloviating, and a good background music.
I see what you did there.
We need a 2X Like button.
Your channel is nice to binge watch this quarantine, a great help for me now that I'm reviewing for boards. Thank you, sir! ❤️👌
Another great video. Keep it up. I will support this channel when I get a job
Liked it!
The Nobel Prize should consider this demo.
This always facinates me
I love this channel , it is in the top list.
Hi , I have been following your channel from a long time , thanks for teaching me a lot during this period....thank you THE ACTION LAB...
Great demonstration.
very short, simple and informative. this is why i love your videos, they are not unnecessarily stretched upto 10 mins.
Oh yeah, Rayleigh scattering. We all, um, we all knew about this already. 😏🤔
Amazing experiment.
*_C.V. Raman was a Indian Scientist, Mathematician, Philosopher, Musician and Professor... He was the very person who discovered Raman Effect_* 🙂
you mean he discovered ramen? :D
@@kjgfalsk surprised he didn't boil the water
Excellent! Simple and clear. Bonus in explaining why sunset look reddish.
Very well done. Would like ro see more on why/how the interaction of light with molecules causes the light to behave in these two ways.
I love your videos man. Ramen scattering :) . Funny AF. It Raman BTW
Thanks for making more of this videos - Light physics. What's the technical word to call it?
Look what I found....Our Mr. scientist as a rock band performer....😅

Optics. Or in Newton's time, Opticks. More generally, electromagnetism.
Thanks for making us smart.
Schools couldn't do that.
Thanks for simple but great informational video
3:03 What's this application called? OMG It's so cool.
That's Space engine, made by a single Russian developer
As Kanishk commented, it's Space Engine. Don't be discouraged by the fact that this app is paid on Steam. Version 0.980 is availiable for free on spaceengine.org IMO this app is worth the money developer asks for. It also have nice VR support - that may be a shameless plug, but I have VR gameplay of Space Engine on my channel. Flying through nebulas in VR is extremely cool.
@@adamo1139 I don't have vr but I love it on flat screen, I have the paid version on steam
its "Google universe"
Universe sandbox
I really love your show, keep doing the great stuff! I must confess though that your voice sometimes reminds me of Lumpy Space Princess from Adventure Time
The sky appears blue due to 2 main reasons
1) The left end of the spectrum i.e the 3 colours blue,indigo,violet have shorter wavelength this causes dispersion of those 3 colours from atmospheric oxygen and nitrogen unlike the red because their wavelength is more compared to left end of colours.
2) Human eye is capable of seeing only blue colour although violet has least wavelength in the spectrum.
actually, we can see violet and that is the reason why the color is named.
what we actually can't see is _ultra_-violet and _infra_ red.
Thanks for the science fair idea
@The Action Lab When I learned Rayleigh scattering from my Electrodynamics textbook, the explanation given says why scattered light is polarized perpendicular to the direction of travel of light. I don't remember what Raman scattering is, but wasn't aware it had its own explanation for the polarization. Makes me wonder what new it adds.
In fact, I've noticed something really cool using the theory behind Rayleigh scattering with lasers. If you shine a laser perpendicular to your camera, the beam will appear brighter when the light is vertically polarized, and it will dim when you twist the laser 90 degrees so it is horizontally polarized. I tried this with my 405 nm laser a while ago and it worked!
*Plot twist: the torch could change colours!*
James is soooooooooooooooooooooooooooooooooo underrated!
This is one of the few places I actually learn something
l have always wondered that,
What a great video!!! Thanks a lot.
Wow... i read about scattering in school... but your demonstration was awesome....
Nice and knowledgeable video, thanks Action lab.😊
Very well explained!
That was a really cool experiment!
ITS LIKE SCIENCE CLASS BUT BETTER !!! and not boring..
I've learned more about physics from this channel than from my school. Thank you so much!!!!
Great presentation.
This is the best explanation
Well actually the spectrum of LED is not exactly similar to sun, but still a good demonstration.
There is a peak on blue wavelength in LED, I wonder how that effects this experiment, if we do this with sunlight too.
The sun is made up of trillions of LEDs. 😁
Wow, that's really cool and amazing! 👍🏻😀
Raman scattering will shift the wavelength a little bit, and therefore the color will be slightly change, on the other hand, the Rayleigh scattering doest change the color.
Wow good info in this video! I always knew the atmosphere scattered light from our Sun but never looked at it like this before. Nice job with the easy home experiment
Visually you replicate this and it makes a lot of sense, thanks! BUT one question, if we see the sun as yellow but see it as white in space like the stars. Then why do we still see stars at night as a white colour? Shouldn't they appear yellow as well in our atmosphere as the sun does?
Wow!
It's really a good demonstration on how we perceive different colours of light.👍👏👏
Mind blown!!
Finally ..... the perfect experiment ..... thank you so much ......
I really appreciate your videos
Excellent, concise, accurate and scientific demonstration!
Excellent video!!
'How to amaze an audience of all ages'
Man you are turning into a muscle monster 💪
those simple experiments that answering simple questions with the use of physics are simple awesome! great video!
Nice information sir....loved your content👌.... Love From India❤️
2 of my favorite stuff from japan are in this video

Under 5minute, like it!
So many things learnt in such a short video. Amazing !
Oh, cool.
I was just wondering this yesterday! Is UA-cam AND you listening to my thoughts?! Lol. This is the ONLY time I’ll say it’s ok! Thanks for the answer!
I love this guy, he's really awesome
Thanks!
I never even noticed the sun looks yellow, it's too bright to look at.
This video was really good I understood what you meant and you did not ramble (like you sometimes can't do in other videos 😂😉)
There are mind boggling forces in the universe we may never understand, like why do people grow moustaches?
LoL
Because Mario thats why
Thanks - this triggered one Question - light from Sun 🌞 is red and orange but same light reflected from 🌕 moon is white ? Why, same light , same atmosphere why different colors. Please help 🥺
You are right about protein molecules being smaller than light wavelength, but milk also contains particles of fat that can be as big as 3 micrometers, making them bigger than light wavelength. In this case it's Mie scattering. Rayleigh scattering is much weaker than Mie scattering, and if it wasn't, we could do this same experiment without milk, with water alone. Otherways, very descriptive and demonstrative, I like it.
If the atmosphere is causing the sun to appear yellow to us, then why do the other stars that are much farther away still appear white through the atmosphere at night?
