I'm crying. I finally understand this after hours of roaming on RU-vid videos. We're studying online, and our professor didn't give us any textbook. He just gave the topic and left us on our own with an assignment. I'm really thankful for these people who share knowledge through the internet. I cannot learn during this season if it wasn't because of teachers in RU-vid like you. Thank you very much.
@@debrachambers1304 hello. Yes i do that. But for people like me who understand better if it's being explained verbally, textbooks can be challenging to study as well, especially when we have deadlines coming up and I can't spend hours on a single topic. I'm not trying to find excuses, I hope you don't think about it that way :< I'm just saying, I'm thankful to those who explain the topics when our own professors don't.
@@grace5447 I understand. I was just responding to the part where you said you weren't given any textbook and letting you know you can still get one easily for free.
Yes. I want to rant because of your comment and yell to the world all the things I've been learning recently. But I'll stick with your comment. The universe is truly magnificent.
@@hambonefakenamington69 My biggest rant has to be why does the Pauli Exclusion principle exist? What is the true reason behind it, the mechanism we understand (or at least we think we do), I want to know why. Also, planck length and time are scary to me for some reasons, but thats another rant.
Have watched this 3D animation several times. It is really beneficial to understand circular polarisation and Stern-Gerlach Experiment. Thank you, Eugene, for your sincere effort.
I recently created a Patreon account for people who want to help support my channel. The link is on my RU-vid home page. Also, in case, you have not already seen them, I uploaded several other videos recently. As always, for each video that you like, you can help more people find it in their RU-vid search engine by clicking the like button, and writing a comment. Lots more videos are coming very soon. Thanks.
why do you make the light passing through perpendicular to the plane of polarizer, it looks as if lights were all blocked but they were going through. my brain is resisting in this visual effect.
The plane of polarization is perpendicular to the direction in which the molecular structure of the polarizer is oriented. This is because the long chains of molecules will _absorb_ any component of the light (with some percent efficiency) parallel to the direction they are oriented, only allowing the component which is _perpendicular_ to their orientation to pass through.
Unified Field is real and the NEW discovery of monopoles made this possible PICTURES of light fields and unified theory works perfectly. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-aw_u7bjqmGU.html
I am just now learning about this in my E and M class, and it is nearly identical to the class lectures that we are taking notes on. I must say, Eugene, I am very impressed by the quality of your videos. You deserve a lot more attention than you are currently receiving.
Wish I had seen this video when I was taking grade 12 physics last year... the stuff would have made so much more sense! Your videos are actually so great they make me love physics
This is really the first video I've seen that explains polarization in a way that I can really understand. Thank you very much. Congratulations. Hope see you in others Physic items
The visual explanation of circular polarization was very good. Now it makes perfect sense how it works, and why it is the same phenomenon as linear polarization.
Wow. This video deserves more recognition. It gave me a full understanding on polarization of electromagnetic waves in 20 min which I have been trying to do for 6 months with textbooks but failed.
Always amazed by the superb 3D animations, simply unthinkable how to make them, not mentioning the nearly 20 different languages of CC which is unseen ever !!! 👍👍👍
All the music in this video is from the free RU-vid audio library, and the names of the songs are the following. Waltz_of_the_Flowers_by_Tchaikovsky Fur_Elise_by_Beethoven Eine_Kleine_Nachtmusik_by_Mozart
I paused the video to comment on how easy the animation makes it for one to grasp and visualize how the different types of polarization come about. Thank you for putting in the effort, really appreciate it.
u deserve much more views and likes.i am a RU-vid science video watcher. There was a science channel named Kurzsegat they changed their channel name to 'in a nutshell' and is running quite successfully. This name Is nice but may be you should try something catchy like the science show or something more catchy just a advice

Nobody has yet explained to me WHY light "chooses" (for lack of a better word) only these 2 planes to be polarized in OUT OF THE UNCOUNTABLY INFINITELY MANY POSSIBLE PLANES THAT EXIST. When I first learned of light waves, I always assumed that the wave pictured was NOT meant to be taken literally but merely as a geometric metaphor/representation of the amplitude of the pulse of light. In other words, I always assumed that the amplitude of a point source of light is radially symmetric and that the magnitude is a sine or cosine function of time & r, not a function of some arbitrary x,y,z coordinates.
I want to make videos like this to explain people really..but I have no knowledge of 3D animation. I can see the hardwork behind this video. Awesome work. You people are guide for future generations..
I always enjoy the videos in which you explain exactly why notions of classical thinking and logic do not work when dealing with Quantum Mechanics. It would be nice if you did something like this for the polarization aspects of light.....beyond just the Quantum Eraser Experiment. I would also enjoy a video on how a computer stores things even if you turn off the power.
thank you for this video ,this is best the video i 've ever seen explaining polarisation of light . this makes me understand how wonderful the physics is !!!!
great video! i got 2 questions: 1)when electro-magnetic field is passing through polizer what is happening to the part of it that doesnt pass through? is it absorbed by the material? or maybe reflected? 2) @ 19:00 u say this phenomena plays a very important role in technology. could u give few egzamples of how is it used??
+TheSara90, thanks for the compliment on the video. In reply to your questions, the electromagnetic wave that does not make it through can be either absorbed or reflected, or a combination of the two, depending on the type of material. Examples of technology where this phenomena is used are liquid crystal displays and 3D glasses. Liquid crystal displays can operate similarly to the example of the three linear polarizers that either allowed light to pass through or block light depending on what the polarizer in the center was doing. Many 3D glasses operate by having the material for each eye pass through or block light depending on its polarization, thereby allowing each eye to see a different image.
Not the electromagnetic field, but the electromagnetic field excitation. The electromagnetic field itself is everywhere all the time. When it is excited, a ripple, a wave is created, which travels through spacetime. That ripple is the lightwave, if it bumps into something, it is the photon. I thought, you asked, what happens to the distorted field, like a field around the magnet, if it is interacting with a polariser lens.
@cairo can you explain the “if it bumps into something, it is the photon"? I thought that lightwave and photon were two different names of the same thing
Your videos help me in understanding difficult concepts of physics like no one else can! Thank you so much for making my concepts so concrete! I would have never had such clarity in science if not for your videos! Amazing
Magnificent,I can not visualise the concept of polarisation and how electric field vector contributes in polarization.Thank you so much for your 3D explanation video.
03:20 - It was a bit unclear to see 3 different magnetic fields without a proper textual explanation, e.g. "electric field 1", "electric field 2" and "resulting electric field"
Yes! I had to watch this video 3 times to make sure I was understanding that part correctly. Still a great video but some more descriptive labels for the waves would have less some of my confusion.
What this video fails to mention is that if you have an electric wave and a magnetic wave whose amplitudes differ and which are not in phase, then the polarization is elliptical. In order to have circular polarization, the amplitudes of the magnetic wave and the electric wave must be equal.
How can the amplitudes differ? I thought all photons have the same amplitude. What does it mean for a photon to have a smaller or larger amplitude? What is an example of a 'real world' example of that?
Well for a single electromagnetic wave the electric field and magnetic field will always be in phase, so idk if that's totally right. But if you meant two different electromagnetic waves of different amplitudes out of phase, then I think you are right. Also it seems the waves need to be 90 degrees out of phase in order to be 'perfectly' circularly polarized. Cheers.
You mention amplitude here, but what about wavelength? 2 photons with differing wavelength would have some sort of irregular polarisation, since the revolving motion will move 360 degrees on 2 different lengths?
@@maltejohnsson8578 interesting! I think they would have some irregular polarization pattern. It certainly wouldn't be 'circular' (i.e. Constant rate of change for electric/magnetic field direction), but the rate of change for direction would vary. Kinda similar to adding sine waves of different frequencies, except in 3d. I could only imagine applying Fourier's theorem to light waves.. Imagine creating a "square" polorization by applying Fourier's theorem.. I'd be very interested to see an animation of that! Or in real life if it's even possible lol
SUPERB... animations and the combination of perfect commentary and background music. I wish ALL RU-vid videos could be like this !!! Thank you so much for your efforts.
I have to say that while the video itself is very clear, most of your last videos are getting boring due to constant repetitions of pretty much the same things. For example, you could have simply said that the wave would rotate the other way if the shift was done for the first wave without going through all that "add like vectors" process. And I think you should consider decreasing time intervals between phrases.
The maker of these videos have great in depth conceptual knowledge and techniques that make students understand everything once and never to forget again. Thank You So Much Eugene
Well done again! Thanks. Like for you. Towards the end it got exciting when mentioned was the challenges to our understanding of nature, and then it ended. Well apparently I must see all the other light videos too. I will, if given time, I will.
I never ever understood circularly polarized light... Thanks for explaining through visualization. And additional thanks for some great piano pieces playing in the background
Thank you so much for creating these amazing videos. Your work is making people's lives better through holistic understanding, not just superficial information.
19:27 So you would use two quarter plates to flip the orientation of the polarized EM wave? As in the "red" arrows are on the right+top quadrant when coming into the first quarter plate, and are on the left+bottom quadrant when coming out of the second quarter plate?
This is by far the best ever explanation of polarization. It lets you understand the topic more intuitively. Thank you Ma'am. Love and respect from INDIA.
extraordinary!!! im surprised as to why this video has 901 likes only.100 % TRUE its the only video that explains polarization as said by Khandnalie. its just WOW!!
Good explanation but it's so show that I felt like light traveling through a medium! And then there was this soothing music which kind of accentuated the ambience in putting me to sleep!
Beautiful. I am neither an animator nor programmer, so I cannot create many visualizations that I would like to do. This is one of those. After this video, I think there can be no one who can not understand polarization.
