Itotally get it. Itsamazing to see aomeone learn something awesome like that. I once explained the size of the universe to my 4 year old nephew and right after he looked up at the sky and said woooaaaahhh!
And here I am, ten years after this was posted, it is still the best explanation of the double slit experiment ever! Now I need to find the episode where you conclude that light also has to be a particle. And then the one where the existence of a photon is dependent on an object it "hits".
@Gabriel Neipp You didn't have to write a long essay on that. I was quite disturbed on how you made such quick assumptions on that old lady just coz you passed 5thGraDe.
The man in the yellow shirt almost made me cry of joy, because it was the most beautiful example of human curiosity and wonder for nature itself that I have ever seen. He was absolutely amazed by what he saw, inmediately proceeded to communicate his experience but the joy that the experience brought to him wouldn't let him wait to see it again, and then the best thing that ever happened to the Universe: the man asked why. That in that order has to be the most beautiful set of emotions that anyone can go through.
The guys reaction in the yellow shirt and blue hat- literally made my day! It’s so rare to observe someone genuinely experiencing amazement. It really is one of the purest forms of joy. So human. So awesome:)
Their reaction shows the difference between making something interesting, and what schools do. All these people made this experiement in school I bet, and nobody even remembers doing it. I learned this in 10th grade. But schools make everything so boring and make everything be a chore that nobody WANTS to learn it. We really need to change the way we teach things, because currently we are just wasting our kids' time.
Actually, the video does not mention that you won't have a "wave pattern" if you use two sources of photons (with the slices). In his experiment on the water, he's using two sources of waves. Particles would not interfere if we did that with light. It looks like a detail but it's a big difference if you really want to understand QM.
@@prashand4899 you dont know if he spends his time learning about other things. Physics isnt limited to the double slit experiment and you can study branches without learning about it.
A lot of people just react with complete disinterest. I think those people unfortunately can't really be helped. But the yellow shirt guy was clearly fascinated. It's a good way to be.
Thanks Veritasium! I was recently studying diffraction for my college entrance exam, and you helped me envision how the double slit experiment actually looks like. This is gonna help me build my concepts
Bhai I am also a Jee aspirant , how ever case performed in this video is a special case because a whitle light consists of various colour with different wavelengths so the is only once central maxima whereas the colour spots are due to individualistic wavelength.
Your coment is unscientific. In fact there are resurch that show how our body and mind actually generate wave lengths in various frequencies. Other resurch shown that people cane experience synesthesia (a mix of the senses). Why not an implefyed sences? The door is open for the deconstruction of preconceved ideas of the world. This is scientific...

Years later people would describe Derek as the man who roamed the streets and talked physics with commoners like philosophers used to, about a few thousand years ago
Except Socrates and philosophers were not meddling with questions pertaining to empirical science. So the comparison only goes so far as him asking questions but not the actual nature of the knowledge or wisdom sought. Philosophy is the love of wisdom and seeks the knowledge of first principles and being as being and the nature of things. Philosophers are not empirical scientists. If I ask what is the nature of water as a philosopher I do not care about it being H2O. That is the realm of chemistry not philosophy.
@@optimoprimo132 well, yes i totally agree... but as you probably know, philosophy and empirical science are sets that intersect, simplistically speaking, its probably more complex than that.... but for example the great mystery: consciousness. well you see things because light falls on your retina, the rods and cons pick those signals up, the optic nerve converts those signals to electrical impulses that then goes to the visual cortex to be processed, and we see it, that sight or the image in our mind can produce different effects, if its a tiger on loose that a person sees, adrenaline and the other hormones get released and speed up the heartbeat, he escapes. this becomes a part of the memory in the hippocampus, and that person tells the story to the others cuz of psychology, he feels the need to share this with everyone, so that he can connect with them, etc..... science seems to creep up in every single question we ask, but even physicists and biologists realize, its not a complete understanding of everything. that person who experienced all that, who is he? is he just a symphony of these synchronized processes, or is they deeper than that.... consciousness is something that cant be explained by the theory of synchronized neurons firing at the right time. just like if you successfully create a simulation of an ocean, by coding all the movements of the water molecules, all of the factors, the environment, the whirlpools, the currents,... the simulation will still be missing the essence, the wetness, its still not real water
@@OhFishyFish still in the middle of the video but aren't waves just another modell like beams? I though they were quantum particles ( excuse my english)
What I like in these videos is the sheer amazement of people when they get the explanation. They're not stupid, they just don't have the same interests nor fields of competences than what the video is about. But they're glad they've learned something and in the end, it's not being smart or stupid that counts, it's learning new things and seeing how cool the world really is.
what concerns me a little is some people would create some nonsense instead of admitting they dont understand something. admitting ignorance is good (ignorance is normal), but pretending to know the answer is not good.
Shaurya Shubham nor so sure that everyone is a genius, but I've met people who were geniuses at having fun... WOW! I've met one who was a genius at having sex, that was heartbreaking... But no, I'm not a genius at anything. Just have a thirst for knowledge and understanding.
A correction. We are all stupid humans, on a cosmic scale there is no difference of intellect between any humans. However some humans are more experienced/trained in some local areas than others. Also, some humans don't train their brain as much as others. This leaves room for diversity of brain activity 😉 ignorant is usually more correct than stupid, but both terms have their use.
The truly mindblowing part of this wasn't even discussed. When you measure any of the photons individually, they all pass through a slit as a particle. The implications of this experiment are beyond fascinating. Quantum physics is trying to tell us that all possible scenarios exist all the time. Our experience as an observer is what determines the path we're experiencing.
Simple answer. Light is like a water, opposite. Depends on how you oberve/interact. They can be looks like particle, or wave Water can moving like a wave. But its particle Light can moving like a particle, but its a wave
@@allvid_ What if I told you that it's the wave using water, causing the water particles to vibrate but not the water itself. Whereas, it's the actual light which has wave or particle property rather than a wave just using it as a medium? 😭
@@chanella3996 I often wonder if we are the shadow of another dimension, limited by this dimension we call space time continuum; and if there is a way to enter that dimension and perhaps travel faster than light in a vacuum. Imagine sound waves traveling through steel rather than air.

Another do-it-at-home experiment that amazed me concerning interferences : Sound interferences. Take 2 loudspeaker (= 2 slits), place them 1 m appart and play one tone (= 1 Wavelenght) . As you move around the loudspeakers you will find dark zones (quiet) and bright zones (loud). Couple of softwares are available on the internet to play around.
I m in 12th class so according..to me its a wavelength ....bcz if we pass colour light through class slab. .its frequency wiilll remain same but Wavelength will change..but still color reamain same thats why frequency is characteristic of light
I was lucky to conduct such experiments when I was so young, 75 years ago. The time gap between 3:24 and 3:52 showing the Yellow shirted man keep going back to see the wonders behind the double split experiment, somehow touched me emotionally, as, effectively, there was a blind man who suddenly began to see the hidden wonders of science, at his age, and slowly began to conceive that there are so many wonderful, majestic activities and processes behind the silence and unlit spaces around us! I loved it when his keenness to learn, and his thirst for more, he forgot about his cap, paused, and quickly corrected the situation, yearning for another opportunity to behold the miracles around him which he never saw before.
That feeling. Life without it is such a waste of time. Everyone is born with this curiosity and fascination and has it as an infant and and later as a kid but most of us lose it later somehow. Keeping it and learning to live with this feeling of excitement of reality around us should be part of the education goals.
It saddens me that there are people who would rather believe in religious dogma and outright ignore science. Because of their beliefs, they have a blatant non-willingness to learn, and because of that, will never see the beauty of science around them. It’s a truly wonderful thing to behold the evidence of science before your eyes, and realizing it has nothing to do with or without a creator; it just is because that is how nature works.
In the experiments of Huygens/Young ,there was no evidence that the claimed interference patterns were not a reflection of mechanical particles toward the back walls reflecting further onto the front walls. They simply assumed that since we see an interference pattern of light on the side of the slits ,that meant that light only was a conglomerate of wave energies. He forgot that photons do not necessarily only enter straight through the slits nicely. From there one went on to the idea of the wave particle duality. (particles only appear if there is only a wave and we look at it) Of course it is way more plausible that the spin mechanics cause the waveform. You will find nobody in CERN agreeing that particle spin doesn't occur... Many particles travelling in a large speed cannot make us detect the pathway perfectly, but it will certainly appear as a wave.
@@acidplasticine What fascinates me about humans is that most are driven by their instincts and their emotions and some are driven by their minds. Though there is no shame in being driven by instincts and emotions the world does not advance much with people driven by their instincts and emotions which are basically irrational and illogical.
@@JanoyCresvaZero It is such a pity that there are many people who like to compete against their fellow humans and they spend all their life exploiting society in earning their living pitting their wits against fellow humans, just distributing emotions to them! Since not so long time ago some people became aware of the wonders behind the silent and invisible processes and activities in the universe and that what we may call science and engineering and mathematics where the latter may not be a natural phenomenon but their operators are very rational, logical and reasoned out rather than dealing with the instincts and emotions of people and social services where all that matters is catering for instincts and emotions. Religions and politics did not do much for the tangible guaranteed comforts of the family and it is when science took over from the emotions of art and religions that the family gained so much to have all the practical tangible guaranteed comforts we now have during our life and not after death.... al because the logic in engineering replaced the emotions in art and religions and politics and other " unguaranteed social services!".

Honestly, I have seen numerous videos and been taught this multiple times before in class, but this video was the one that finally had me understand it. All of the other ones kept going into abstracts over light as a wave, but simply demonstrating it and then showing it on a pond was what actually helped it click for me.
Peter Bonnema A photon is not an element, it is a "gauge boson". Here is the Standard Model for you: upload.wikimedia.org/wikipedia/commons/thumb/0/00/Standard_Model_of_Elementary_Particles.svg/2000px-Standard_Model_of_Elementary_Particles.svg.png
Joe Seph I know, that's why I said 'elementary particle' which in modern language means a particle that cannot be separated into different parts. I made the comment because this description used to be the meaning of the word atom or element.

Just learnt about YDSE today in school, and came back to watch this video. Crazy how great quality it is, even though it was made 10 years from now! You're amazing, Derek!
To me, the most important part was the fact that he explained exactly what was happening to each one of the participants. And, man... You gotta start as the yellow shirt guy if you wanna become the Veritasium guy. That's for sure.
what he said was a pretty good practical definition of it. Light bouncing off things is what allows us to see them, most of us wouldn't even be aware of light if it wasn't for the fact that we have these organs in our heads that make use of it. If everyone was blind we might still have an advanced society, perhaps underground, and if you asked the guy in the hat the same question he would instead have said something like "it is the thing that burns your skin when you go above ground for too long". These people might not have discovered light and started to study it until well into the modern era. And what if we were blind and had fur to protect us from sunburn, we might not even have discovered light yet!
Doesn't mean we can't see light that we won't be able to discover it. We were not able to understand and see a lot of things, but we still discovered them.
postvideo97 I never, at any point, said that we wouldn't have discovered it. I said that we probably would have but we might not have. You neither read what I said fully nor understood my point.
Well, she is kind of right. Photons are a fundamental particle. I think that is what she was getting to. The standard model is sometimes called the physicist's periodic table.
@@Moonlakes Photons, which is the stuff light is made of, are elementary particles. So here is the comparison: elementary particles (like photons) are for the standard model of particle physics what elements are for the Mendeleev's periodic table. Do you really think she thought light is like oxygen? Of course not. She was saying, in a layman's way, that inferring to photons being an elementary particle.
Got the most clear explanation of what wave optics focuses on......now it's not an imagination ! It has a clear picture of what we study in our books 😇 thanku you so much GG sir ❤️❤️
To make the experiment more compelling, they should allow the subjects to look through the box with only one slit open. After they see, ask them what they think is going to happen when they open the other slit (the second slit). That way the can truly see the difference between them. But still an awesome video.
The guy in the yellow shirt made me understand why people become teachers. He literally shone up like a child, inspired and awestruck by the beauty of nature and physics, and just kept on asking questions on the nature of light. It was amazing to watch!
One of my most exciting art experiences was seeing Michelangelo's sketches for paintings in real life. For some reason I don't really care about the fully rendered color paintings, but the minimalist sketches with just a few lines blew me away. I bet it could be something akin to that experience, seeing the actual original from the man himself.
I'm at highschool, doing my physics presentation about light diffraction right now, and this video is absolutely amazing, best explanation I've found so far!
It's not. Does not explain why the pattern happens. Nothing about the surface of those slits difracting photons causing them to interact with each other. Also the wave-like function is there bc billions of photons pass through the slits in a second. If only one photon was shot through you would see one dot as if it was detected by a detector.
@@va_nda Nope it does, that water waves demonstration was all that was needed to understand the principle reason behind ydse/ interference. But yes it isnt enough to study deep into the topic
+Karl Hiramanek if you weren't so quick to feel superior you might've realized that the word "element" has more than one definition, one of which (according to merriam-webster) reads, "a particular part of something (such as situation or activity)"....... and light is undeniably a particular part of our experience. so maybe the girl isn't the one with the closed mind in this situation, lol.
+someone else The definition you are referring to is elements of a group. That's a completely different meaning. Since this question was in the context of science, it's implied she's referring to elements, as in those in the periodic table. I doubt she was being eloquent enough in casual speech to say, "Light is an element of our existence." It's more likely she just said a stupid statement, as this video was purposely edited to make all the interviewees seem stupid.
@Adolf Hitler i said that it makes me uncomfortable seeing many people stand very close. why? because in a pandemic that has negative implications, which is completely true.

And here I am, ten years after this was posted, it is still the best explanation of the double slit experiment ever! Now I need to find the episode where you conclude that light also has to be a particle. And then the one where the existence of a photon is dependent on an object it "hits".
Hi it is a very fascinating experiment

The man in the yellow shirt almost made me cry of joy, because it was the most beautiful example of human curiosity and wonder for nature itself that I have ever seen. He was absolutely amazed by what he saw, inmediately proceeded to communicate his experience but the joy that the experience brought to him wouldn't let him wait to see it again, and then the best thing that ever happened to the Universe: the man asked why. That in that order has to be the most beautiful set of emotions that anyone can go through.

Their reaction shows the difference between making something interesting, and what schools do. All these people made this experiement in school I bet, and nobody even remembers doing it. I learned this in 10th grade. But schools make everything so boring and make everything be a chore that nobody WANTS to learn it.

Can confirm, was the experiment.
Cue scene from "Young Frankenstein"
*IT'S ALIVE!!!*
Actually, the video does not mention that you won't have a "wave pattern" if you use two sources of photons (with the slices). In his experiment on the water, he's using two sources of waves. Particles would not interfere if we did that with light.
It looks like a detail but it's a big difference if you really want to understand QM.

@@daviddedick14 probably but Socrates was kinda douche though, intelligent but douche.
Except Socrates and philosophers were not meddling with questions pertaining to empirical science.
So the comparison only goes so far as him asking questions but not the actual nature of the knowledge or wisdom sought.
Philosophy is the love of wisdom and seeks the knowledge of first principles and being as being and the nature of things.
Philosophers are not empirical scientists. If I ask what is the nature of water as a philosopher I do not care about it being H2O.
That is the realm of chemistry not philosophy.
@@optimoprimo132 makes total sense
@@optimoprimo132 well, yes i totally agree... but as you probably know, philosophy and empirical science are sets that intersect, simplistically speaking, its probably more complex than that.... but for example the great mystery: consciousness. well you see things because light falls on your retina, the rods and cons pick those signals up, the optic nerve converts those signals to electrical impulses that then goes to the visual cortex to be processed, and we see it, that sight or the image in our mind can produce different effects, if its a tiger on loose that a person sees, adrenaline and the other hormones get released and speed up the heartbeat, he escapes. this becomes a part of the memory in the hippocampus, and that person tells the story to the others cuz of psychology, he feels the need to share this with everyone, so that he can connect with them, etc..... science seems to creep up in every single question we ask, but even physicists and biologists realize, its not a complete understanding of everything.
that person who experienced all that, who is he? is he just a symphony of these synchronized processes, or is they deeper than that.... consciousness is something that cant be explained by the theory of synchronized neurons firing at the right time. just like if you successfully create a simulation of an ocean, by coding all the movements of the water molecules, all of the factors, the environment, the whirlpools, the currents,... the simulation will still be missing the essence, the wetness, its still not real water

What I like in these videos is the sheer amazement of people when they get the explanation. They're not stupid, they just don't have the same interests nor fields of competences than what the video is about.
But they're glad they've learned something and in the end, it's not being smart or stupid that counts, it's learning new things and seeing how cool the world really is.
what concerns me a little is some people would create some nonsense instead of admitting they dont understand something. admitting ignorance is good (ignorance is normal), but pretending to know the answer is not good.
Shaurya Shubham nor so sure that everyone is a genius, but I've met people who were geniuses at having fun... WOW! I've met one who was a genius at having sex, that was heartbreaking...
But no, I'm not a genius at anything. Just have a thirst for knowledge and understanding.
A correction. We are all stupid humans, on a cosmic scale there is no difference of intellect between any humans. However some humans are more experienced/trained in some local areas than others. Also, some humans don't train their brain as much as others. This leaves room for diversity of brain activity 😉 ignorant is usually more correct than stupid, but both terms have their use.
The truly mindblowing part of this wasn't even discussed. When you measure any of the photons individually, they all pass through a slit as a particle. The implications of this experiment are beyond fascinating. Quantum physics is trying to tell us that all possible scenarios exist all the time. Our experience as an observer is what determines the path we're experiencing.
Simple answer. Light is like a water, opposite. Depends on how you oberve/interact. They can be looks like particle, or wave
Water can moving like a wave. But its particle
Light can moving like a particle, but its a wave

Who are here from rajwant sir's lecture??
Me
I was lucky to conduct such experiments when I was so young, 75 years ago. The time gap between 3:24 and 3:52 showing the Yellow shirted man keep going back to see the wonders behind the double split experiment, somehow touched me emotionally, as, effectively, there was a blind man who suddenly began to see the hidden wonders of science, at his age, and slowly began to conceive that there are so many wonderful, majestic activities and processes behind the silence and unlit spaces around us! I loved it when his keenness to learn, and his thirst for more, he forgot about his cap, paused, and quickly corrected the situation, yearning for another opportunity to behold the miracles around him which he never saw before.
That feeling. Life without it is such a waste of time. Everyone is born with this curiosity and fascination and has it as an infant and and later as a kid but most of us lose it later somehow. Keeping it and learning to live with this feeling of excitement of reality around us should be part of the education goals.
It saddens me that there are people who would rather believe in religious dogma and outright ignore science. Because of their beliefs, they have a blatant non-willingness to learn, and because of that, will never see the beauty of science around them. It’s a truly wonderful thing to behold the evidence of science before your eyes, and realizing it has nothing to do with or without a creator; it just is because that is how nature works.
In the experiments of Huygens/Young ,there was no evidence that the claimed interference patterns were not a reflection of mechanical particles toward the back walls reflecting further onto the front walls.
They simply assumed that since we see an interference pattern of light on the side of the slits ,that meant that light only was a conglomerate of wave energies. He forgot that photons do not necessarily only enter straight through the slits nicely. From there one went on to the idea of the wave particle duality. (particles only appear if there is only a wave and we look at it) Of course it is way more plausible that the spin mechanics cause the waveform. You will find nobody in CERN agreeing that particle spin doesn't occur... Many particles travelling in a large speed cannot make us detect the pathway perfectly, but it will certainly appear as a wave.
@@acidplasticine What fascinates me about humans is that most are driven by their instincts and their emotions and some are driven by their minds. Though there is no shame in being driven by instincts and emotions the world does not advance much with people driven by their instincts and emotions which are basically irrational and illogical.
@@JanoyCresvaZero It is such a pity that there are many people who like to compete against their fellow humans and they spend all their life exploiting society in earning their living pitting their wits against fellow humans, just distributing emotions to them! Since not so long time ago some people became aware of the wonders behind the silent and invisible processes and activities in the universe and that what we may call science and engineering and mathematics where the latter may not be a natural phenomenon but their operators are very rational, logical and reasoned out rather than dealing with the instincts and emotions of people and social services where all that matters is catering for instincts and emotions. Religions and politics did not do much for the tangible guaranteed comforts of the family and it is when science took over from the emotions of art and religions that the family gained so much to have all the practical tangible guaranteed comforts we now have during our life and not after death.... al because the logic in engineering replaced the emotions in art and religions and politics and other " unguaranteed social services!".

I really expected him to say something smart.
I died when I heard that.
what he said was a pretty good practical definition of it. Light bouncing off things is what allows us to see them, most of us wouldn't even be aware of light if it wasn't for the fact that we have these organs in our heads that make use of it.
If everyone was blind we might still have an advanced society, perhaps underground, and if you asked the guy in the hat the same question he would instead have said something like "it is the thing that burns your skin when you go above ground for too long". These people might not have discovered light and started to study it until well into the modern era. And what if we were blind and had fur to protect us from sunburn, we might not even have discovered light yet!
Doesn't mean we can't see light that we won't be able to discover it. We were not able to understand and see a lot of things, but we still discovered them.

Yess
Yessss
I'm actually really amazed that none of those people didn't know about that. I thought everybody should know this since school.
"...and the Spirit of God was hovering over the waters."
fritt wastaken I would just assume that the video was edited to take out all the people who knew of the experiment.
fritt wastaken Ok kids we're going to learn about light and what is it's reaction to the universe.
Yeah, no.
Xevamystic yes actually
I mean, yes high school and collage, but not elementary or middle. Its a deep topic for them.
To make the experiment more compelling, they should allow the subjects to look through the box with only one slit open. After they see, ask them what they think is going to happen when they open the other slit (the second slit). That way the can truly see the difference between them. But still an awesome video.
Try it with electrons instead of photons, you'll have the same pattern even with only one slit open

The guy in the yellow shirt made me understand why people become teachers. He literally shone up like a child, inspired and awestruck by the beauty of nature and physics, and just kept on asking questions on the nature of light. It was amazing to watch!

4:50 This is the best visual explaination of the double-slit experiment I've ever seen
Update: The Yellow t-shirt guy has reached the 4th dimension and is researching on experiment analogous to YDSE over there.
seriously???
@@pratikakumar8663 yes Pratika he lives in the 4th dimension now. He always knew he would be there, which is everywhere
Yea that's why we see paranormal activities which are nothing but his experiments to move things from 4th dimension through our 3 dimensional space.
I like that you can see he’s getting emotional reading the notes in the vault. What an experience that must have been!
One of my most exciting art experiences was seeing Michelangelo's sketches for paintings in real life. For some reason I don't really care about the fully rendered color paintings, but the minimalist sketches with just a few lines blew me away. I bet it could be something akin to that experience, seeing the actual original from the man himself.
What do you mean “ notes in the vault “ ?
@@MAsWorld1 at the beginning they go into a vault and read the original hand written experiment from 1803
RJ sir really said
Pw assemble
I'm at highschool, doing my physics presentation about light diffraction right now, and this video is absolutely amazing, best explanation I've found so far!
It's not. Does not explain why the pattern happens. Nothing about the surface of those slits difracting photons causing them to interact with each other. Also the wave-like function is there bc billions of photons pass through the slits in a second. If only one photon was shot through you would see one dot as if it was detected by a detector.
@@va_nda I mean sure but the experiment was to just show a very simple concept to the average person, not a physics student.
@@va_nda Wrong. One photon would still produce an interference pattern.
What does only one slit produce in the box? I.e. no second slit for the "waves" to overlap.
@@va_nda Nope it does, that water waves demonstration was all that was needed to understand the principle reason behind ydse/ interference. But yes it isnt enough to study deep into the topic
"What is light?"
"Isn't it an element?"
I don't want to live on this planet anymore.
+Karl Hiramanek I thought the "auras" lady was way worse
+Karl Hiramanek if you weren't so quick to feel superior you might've realized that the word "element" has more than one definition, one of which (according to merriam-webster) reads, "a particular part of something (such as situation or activity)"....... and light is undeniably a particular part of our experience. so maybe the girl isn't the one with the closed mind in this situation, lol.
+someone else The definition you are referring to is elements of a group. That's a completely different meaning. Since this question was in the context of science, it's implied she's referring to elements, as in those in the periodic table. I doubt she was being eloquent enough in casual speech to say, "Light is an element of our existence." It's more likely she just said a stupid statement, as this video was purposely edited to make all the interviewees seem stupid.
And so begins a huge youtube argument^
***** If you take an art degree, you're a complete idiot.
Ahhh the days before COVID - when you could shake someone’s hand
seeing these video makes me so uncomfortable. like... don't stand so close, please!
Remembering the good old days.. When people could touch one another... 😔
@Adolf Hitler did i say it's the black death?
@Adolf Hitler i said that it makes me uncomfortable seeing many people stand very close. why? because in a pandemic that has negative implications, which is completely true.
We have never stopped shaking hands
