For anyone trying to find the next video about how photons are also waves: th-cam.com/video/iyN27R7UDnI/w-d-xo.html (When videos are older like this, it's almost impossible to find their follow-up videos.)
Ocean waves with longer periods carry more energy and travel faster. In contrast, light maintains a constant speed; the shorter the period, the more energy it exhibits during collapse. Therefore, it cannot be described as a wave, but an alternative term may be utilized.
Indeed. It's rich in details and it's clear to a level I didn't even think possible. Nick is the man for concise and precise explanations. Also animation quality went up again.
@Johnny Doeboy the electromagnetic field is the does as a byproduct of electromagnetic radiation As for science being dumbed down Im pretty sure this show is for kids I mean he's a guy in a lab coat with a bat man shirt making youtube videos for free on the internet are you expecting to watch his video an then get a science degree?
Steak Electron refers to a small wave in the electron field or a particle (particles are localized waves in the field). Fields are basically plains of existence for waves. The waves are energy. Fields do have their own energy called vacuum energy or zero-point energy. This energy is always there and cannot be taken away. If you try to, the field will make a lower vacuum energy. The vacuum energy is the baseline energy. There will be a little uncertainty in the energy (and everything else) in the field. Just a question but do the dump trucks move with the wave or do the dump trucks just go up and down? Btw I get that the field is waving and causing the action.
Johnny Doeboy I get that you have a large emphasize on electrons aren’t hard balls but rather deformations of the electron field. You don’t need to call me out for being a random guy. We are all random guys learning about great discoveries together. Not everybody is right. And most likely our ideas will be seen as basic and outdated like the four giants. The four giants of electricity and magnetism and such were great at manipulating the microscopic world to create amazing inventions but their ideas are only stepping stones to the achievements we have now and we will be stepping stones for the next generation.
By now it seems like you could fill up an entire beginners lecture or high school course with your videos and, even without covering every technical detail, students would learn more and understand it better than by listening to most teachers. Seriously, how is it that you manage to explain the essentials of a topic every time so on point
One thing I like about this channel is that you answer questions that are on my mind but other sources fail to because they seem like dumb questions. Like what happens to the energy of the wave? But it's not dumb it's just that you actually understand your audience. Great work. Keep it up, please.
I've watched probably 30 videos on the double slit experiment, and none of them, NOT ONE, explained how photons are just waves and how the field is one entity and that is why it can interfere with itself or that superposition and interference are linked. Instead they all seem to give into some sort of mysticism and woo factor. You rock dude.
Shooting other particles (electrons, atoms, molecules) through those slits creates the same interference pattern, so... you mean those particles are just waves?? The woo factor is still there, the quantum physics still has some mysticism.
I'll make a compliment that I should've made a long time ago. I appreciate quite a lot your lessons, they're among the best I've seen in my life. The most impressive part of all this is that it's still common among the population to think that there isn't much skill involved in helping others, explaining something, teaching someone. And many think that expertise on the subject is the only skill needed to teach well, ignoring the deep needs of empathy skills, communication and linguistic flexibility, and many others. It's because of this common misconceptions that STEM teachers around federal universities here can be so bad at teaching sometimes. No matter how ingenious and great they are at research, they can still be dickheads with students. And consciously or unconsciously, you've proven to know all this and much more than me about teaching strategies and skills. Your empathetic skills and considerations towards the viewers interests and doubts are strong, and one of your best assets. The best part of this is that you also seem to go pretty deep on your knowledge of physics, enough for you go beyond the average teaching youtuber, and yet, you maintain your ability to teach properly that complex knowledge to your viewers, showing great skills to simplify and make concise extremely difficult concepts, enough for an interested student like me to understand. Thanks Nick, keep being great.
Good point. One thing that students don't realize is that public school teachers are actually certified teachers (with buttloads of training). College professors/ instructors are not trained to teach (unless they were former public school teachers). That's the main reason they are so horrible.

Steve Dixon If one puts an Avalanche PhotoDiode in a place where there’s an EM field, occasionally there will be an "avalanche" of current: the device was designed to do that occasionally, so it does it occasionally. If you put the APD in a different place, you get more or fewer avalanche events, but what causes that? Was it because there are photons or was it because the APD was designed to do that? If you look at the electrical signal much more closely, it’s not really an absolutely sudden event on the signal line: it ramps up very fast, but it’s not instantaneous. All modern experimental apparatus is the same: signal lines into computers, attached to exotic materials that are driven by exotic electronics. Quantum theory doesn’t necessarily talk about "collapse" during measurement, it can also be taken to describe and predict the statistics one will see of everything that happens on a signal line, and jumps are only the first level of detail about what the signal level does picosecond by picosecond. Sorry: you asked a good question and I’ve given you my very idiosyncratic answer (and compressed enough, as well, that it’s likely incomprehensible.)
Yeah he left that bit out of the explanation of the double-slit, which is honestly one of the main points of the experiment, and opened the door to the whole field of quantum physics. Unless we figured out quantum physics over the last year or so, I always thought the door was still open as far as what light is, depending on what interpretation you used. In most, it seems to be that light is both. The most-accepted Copenhagen interpretation states that light is essentially a wave that becomes a particle. The pilot wave theory believes that light is essentially a particle that is pushed by a wave, so in effect, it's both. That being stated, we still haven't figured out which quantum theory is the correct one, so it's still largely up in the air. It is clear it exhibits behavior of both though.
An actual wave. A wave in the e.m. field. That animationscreen with all the points and crosses, that animates the e.m.field while a wave is passing through it.
Looking forward to the next video sinse my professors insist that there is a wave particle duality which you have covered before. Is it posible to describe radiation pressure which is calculated in statisical mechanics in terms of waves? Or is it because pressure, in general like temperature, only makes sense as a statistical property? Keep up the great work! The attention to detail is superb! Edited to fix gammatical error that I spotted.
What a coincidence! This question was lurking inside my head all day as I started learning more about quantum mechanics and the nature of light. And just when I thought I could never get it, this remarkable video changed it all! Thanks Mr. Lucid!!
Your animations are getting better and as usual i am left with more questions in my mind like - if light is an electromagnetic wave due to this interference pattern should we also consider other particles like electron as an wave in electrostatic field or both electron and photon as particles due to excitation in their quantum fields?(electromagnetic field vs photon quantum field) please answer.
You should definitely consider all quantum particles to be wave-like disturbances in their own quantum fields (photons in the photon/EM field, electrons in the electron field, etc.) th-cam.com/video/Y7Ac8zKTD-E/w-d-xo.html
Hello, I'm a telecommunications Engineering student so basically anything wave related is what I know. I understand how electromagnetic field work and all. But the question I keep asking that I never get an answer for is: what is the electromagnetic field exactly? I know all the math and how it works but what is it EXACTLY? Like physically? What is the nature of the field that can be disturbed by a photon? Those arrow we represent coming out or in a charged particle, what do they represent physically? I got into some quantum mechanics stuff to help me understand but nope, It made it complicated even more.
You ask a difficult question. What is the electromagnetic field exactly? It’s difficult to answer questions about something that is considered a fundamental fact of the universe. First, a field is just a name we use for the collection of all points in space that we can associate some number to, like temperature or pressure or electric push/pull, usually more than one number and sometimes with a direction. It’s an abstract mathematical entity. The electromagnetic field has numbers like energy, momentum (with a direction), amplitude, wavelength, and frequency. This field can be viewed as a combination of a stronger electric field and a weaker magnetic field that both have magnitudes and directions of influence (the arrows). Oscillating charges produce variations in the electric and magnetic fields that may be regarded as waves, the aforementioned numbers change from moment to moment and place to place in a self-replicating fashion influenced by its neighbors. At a quantum level, the numbers exist only in a superposition and do not change (or don’t have values at all), they have probabilities that change instead. Energy is quantized as well. What exactly underlies a quantum field if anything, such that it can have probabilities at each point in space, isn’t clear. I think it is just about geometric relationships between things, or places where things could be. So a field just isn’t physical. It’s a background description of how interactions can play out. Sorry that’s the best I can do. Edit: The electromagnetic field isn’t caused by a photon. The field is an independent thing. A photon is just a persistent wave-like disturbance in some part of the field.
I've finally found some time to translate this video into Hebrew. In my opinion, the double-slit experiment is one of the most intriguing & fascinating science experiments ever. I've done it myself few times & it's mind-boggling! This experiment is not just about waves or photons, but about our very own human fallibility of grasping intellectually such phenomenon in nature. So much so, that there are still scientists who try to disprove the duality of particles(Including photons). I could have lectured for hours - just on this experiment. Great video & cheers! Keep up the good work! You and your twin-dimensional body ^_^
I had a chemistry lab where elements had unique color gradient when using a diffraction slide. It mentioned light was a wave and the relationship of the electromagnetic spectrum.
Did you ever get around to doing this experiment with a fog or smoke machine after all? Your visual representations are highly reminiscent of a conversation we had a while back. Anyway, another awesome video. Also, have you ever thought of passing the beam through a strong magnetic field just to see if it would affect the diffraction pattern?
The Science Asylum I thought playing with lasers, dangerous chemicals, and confusing your friends was the only reason to get into the sciences? My life is a lie!
Awesome video as always!! Can you explain why the interference pattern disappears when you observe individual photons after they went through one of the slits? Instead you get two discrete lines on the screen in that case. Is that quantum weirdness? PLEASE TELL US!!!
You can't compare the 1800s version of the EM field with the 1900s version of the EM field like your question suggests. That's not how photons work. th-cam.com/video/iyN27R7UDnI/w-d-xo.html

Therefore, it cannot be described as a wave, but an alternative term may be utilized.

Finally someone explains this so it can be clear! Thanks Nick.
Thank you for the gret work ! Love it
Awesome !! As always.
I love you, you deserve far more subs than you have
this guy works for his money nicely
This is amazing!!!!
The video's really gooood!!!
You make things simple even for a beginner like mee....
Nice video. I hope you continue about photons in later videos.
Another great video!
Love these vids and your work so much!!! Quick question, how do the waves interfere with each other if singular photons are shot out?
I will answer that in my next video :-)
@@ScienceAsylum AAA you're the best! Ty
Hello, I'm a telecommunications Engineering student so basically anything wave related is what I know.
I understand how electromagnetic field work and all. But the question I keep asking that I never get an answer for is: what is the electromagnetic field exactly?
I know all the math and how it works but what is it EXACTLY? Like physically? What is the nature of the field that can be disturbed by a photon? Those arrow we represent coming out or in a charged particle, what do they represent physically?
I got into some quantum mechanics stuff to help me understand but nope, It made it complicated even more.
You ask a difficult question. What is the electromagnetic field exactly? It’s difficult to answer questions about something that is considered a fundamental fact of the universe.
First, a field is just a name we use for the collection of all points in space that we can associate some number to, like temperature or pressure or electric push/pull, usually more than one number and sometimes with a direction. It’s an abstract mathematical entity.
The electromagnetic field has numbers like energy, momentum (with a direction), amplitude, wavelength, and frequency. This field can be viewed as a combination of a stronger electric field and a weaker magnetic field that both have magnitudes and directions of influence (the arrows). Oscillating charges produce variations in the electric and magnetic fields that may be regarded as waves, the aforementioned numbers change from moment to moment and place to place in a self-replicating fashion influenced by its neighbors. At a quantum level, the numbers exist only in a superposition and do not change (or don’t have values at all), they have probabilities that change instead. Energy is quantized as well.
What exactly underlies a quantum field if anything, such that it can have probabilities at each point in space, isn’t clear. I think it is just about geometric relationships between things, or places where things could be. So a field just isn’t physical. It’s a background description of how interactions can play out.
Sorry that’s the best I can do.
Edit: The electromagnetic field isn’t caused by a photon. The field is an independent thing. A photon is just a persistent wave-like disturbance in some part of the field.
I've finally found some time to translate this video into Hebrew.
In my opinion, the double-slit experiment is one of the most intriguing & fascinating science experiments ever. I've done it myself few times & it's mind-boggling!
This experiment is not just about waves or photons, but about our very own human fallibility of grasping intellectually such phenomenon in nature. So much so, that there are still scientists who try to disprove the duality of particles(Including photons).
I could have lectured for hours - just on this experiment.
Great video & cheers! Keep up the good work! You and your twin-dimensional body ^_^
Thank you for translating!
Wow crazy scientist explaining much better than normal man.
I can't wait for next time. I love this guy.
I had a chemistry lab where elements had unique color gradient when using a diffraction slide. It mentioned light was a wave and the relationship of the electromagnetic spectrum.
Light is one of my favourite subject in physics. I'm looking forward for the quantum mechanical part!
Did you ever get around to doing this experiment with a fog or smoke machine after all? Your visual representations are highly reminiscent of a conversation we had a while back.
Anyway, another awesome video. Also, have you ever thought of passing the beam through a strong magnetic field just to see if it would affect the diffraction pattern?
I remember the conversation. I'm not much of an experimenter though. Not really my thing.
The Science Asylum I thought playing with lasers, dangerous chemicals, and confusing your friends was the only reason to get into the sciences?
My life is a lie!
Awesome video as always!! Can you explain why the interference pattern disappears when you observe individual photons after they went through one of the slits? Instead you get two discrete lines on the screen in that case. Is that quantum weirdness? PLEASE TELL US!!!
Next video :-)
Very informative , good make more videos
Very nice animations about interference. I always wondered: how many wavelengths of electromagnetic field makes up a photon?
You can't compare the 1800s version of the EM field with the 1900s version of the EM field like your question suggests. That's not how photons work. th-cam.com/video/iyN27R7UDnI/w-d-xo.html
