Your explanation, the model of sliding perpendicular E fields, and the demonstrations REALLY helped me understand. ChatGPT's explanation alone wasn't clear enough for me.
cool. thanks for the explanation! the animation you had on your cell phone was more informative than the red ribbon in terms of explanation the vector sum. but there were a lot of other cool explanations in this video. especially the movie theater glasses.
perfect explanation,the most curious thing i learned is that you done in theatre closing one eye.i will also try that one next time in the theatre .thanks!!!!!
The sound wave has two types: compress-wave(P-wave) and shear-wave(S-wave); P-Wave means medium particles oscillate along the propagating direction; S-wave represents particles oscillating perpendicular to the propagating direction. It seems that sound is "polarized", but we do not sense it: because we can only hear P-wave. (S-wave cannot travel through fluid, e.g. air, water, ...)
I wish this video was twice as long and had gone into twice as much detail about circular polarization and how exactly one of the light components is slowed down by a quarter phase. But I appreciate the explanation.
Your model of a wave is very good. The moment you switched it to the circular polarized wave was like boom and suddenly it made sense to me why the iPhone display did not turn black. It is because the circular polarized light always has an amplitude isn't it? I mean the function has no roots. Am I correct with this?
I think that linear polarizers also block out a gradation of light up to a 45-degree angle. Light waves are not oriented horizontally and vertically, perpendicular to their direction of travel. If it were orientated in such a way, you would get light seepage when you spun your stack of polarizers around at different angles. And that's not all. They also block shear in a gradation up to a 45-degree angle as light travels omni directionally.
"My left ear....." - it was so interesting that I didn't even notice that is was shifted to the left. Someone look for a content and someone to find what's wrong.
Regarding the experiment with the mirror and 3-D glasses, that demonstration is misleading in my opinion and needs to be clarified. It's true that if the experiment is done with 3-D glasses that are circularly polarized, then the lens over the open eye will appear darker in the image reflected from the mirror than the lens over the closed eye. However, if linearly polarized 3-D glasses are used, then the lens over the closed eye will appear to be darker in the reflected image. I think he should have mentioned that in BOTH cases one eye will appear darker and the only way to distinguish the linearly polarized glasses from the circularly polarized glasses is to pay attention to which eye looks darker. In my opinion, people who have not done this experiment with both types of 3-D glasses will come away from this demonstration thinking that one lens will only look darker in the mirror if circularly polarized glasses are used and that is not true.
yeahhhahahahahaha that's amazing. it's always exciting for me to wonder and see how the effects observable to us can be transmitted to the camera (and by extension, to other corresponding devices too)
1. Is a linear polarizer defined by the electric or magnetic field, and is it defined by what it transmits or what it blocks? (a green color filter looks pink, for example) 2. where can i find more elaboration about the physics of the circular filter itself? 3. What experiments can I do to correctly define the polarity of light (or the filter) that I have? Am I looking at a vertical electric field? Is the electric field that bounces off a plane perpendicular or parallel to the plane?
1. Don't confuse a colour filter for a polarising filter. Colour filters work by absorbing a CERTAIN WAVELENGTH of light: if it absorbs blue and you shine white light through it, what you will see is the white light minus the blue light = red. Polarising filters slow down / attenuate light of ALL WAVELENGTHS: they just need to be travelling in a PLANE specific to the PLANE of the polarising filter 2. I'm sure you can find loads on the internet (sorry but google can answer that one) 3. a) He already answered this in the video b) The light has a net sum vector in a certain direction: but rotating the polarising filter you can see which direction that is c) Not sure what you mean by this.
I’ve come to realize that I’m not necessarily stupid, I’ve just had terrible teachers. Complex topics only seem like such because the people teaching them to me don’t fully grasp what they’re speaking of. Most proficient practitioners don’t become teachers. The key to intelligence is finding the right teachers. A good teacher makes a worlds difference.
As you are clearly the Chevy Chase of science, I hope you begin to include complimentary pratfalls in each video...thank you in advance...(and excellent video)
Thankyou so much for this very nice video first, for a long time i am looking for what is that at the 4:05 your right hand take down for the 3D glasses, I am really want to know where can buy that plastic (that looks no color one) , cause i am want to make the Circular Polarization. thankyou again !
very good explanation! but to nitpick a bit, i think we learned that the speed of light is actually always 300000 km/s but what actually slows down the light is how long it takes for the light to transmit the energy in an atom of the given substance. correct me if i am wrong, but isn't that what actually causes the "lower speed of light" in optical denser substances?
my left ear is thankful for this video!
oh good, my earphones aren't broken
:D
Unfortunately, my left side of my headphones don't work :(.
And my right😂
@@ammarraza1956 due to overuse, I hear less by a factor
That's brilliant. A not so intuitive phenomenon explained with such simplicity.
Finally a video that makes sense of this phenomenon, and doesn't just say 'it's another type of polarisation'.
I love it! Explained in such an easy way!
The connect the string analogy really helped me wrap my head around the vector motion, thanks!
I particularly like the sliding white E cardboard wave to show 90 deg. phase shift. Well done!
Great presentation. Informative and interesting. Some subtle humour appreciated! Thanks.
Bro you explained literally everything I wanted to know AND in a way that allows me to understand how to use them effectively. Thank you so much.
Most professional video lesson I have ever seen on polarization wave shape!
You're so weird I love it!! Keep the vids coming
simple explanation, great visual. u the man
Woow ......
Just amazing......
❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️
That was one nice presentation !! Congrats for the good work !!!
Absolutely brilliant!
Best explanation online! Thank you one million times
Your explanation, the model of sliding perpendicular E fields, and the demonstrations REALLY helped me understand. ChatGPT's explanation alone wasn't clear enough for me.
That was absolutely awesome! thank you!
WoW, Saved a Ton of reading with this brilliant video
excellent demonstration you make to understand the polarization ..thanx
IDEAL presentation!
Brilliantly explained!
cool. thanks for the explanation! the animation you had on your cell phone was more informative than the red ribbon in terms of explanation the vector sum. but there were a lot of other cool explanations in this video. especially the movie theater glasses.
Explained so well!
you changed my life
Wow Amazing video ever... I like it
Best explaination yet 👌👌
perfect explanation,the most curious thing i learned is that you done in theatre closing one eye.i will also try that one next time in the theatre
.thanks!!!!!
i like the video how he asks question how we r sure than shows it. Making it a perfect blend of curiosity followed by solution
This would be one of best explanations ever. Thanks professor.
Thanks for the comments - I only have a left ear and thought the video was a bust. Now I know I just need to hear it in stereo or without cans at all.
Wow, very impressive explanation.
Great informative video. Was the sound for it polarized as well? My left ear is receiving one component only ;)
The sound wave has two types: compress-wave(P-wave) and shear-wave(S-wave); P-Wave means medium particles oscillate along the propagating direction; S-wave represents particles oscillating perpendicular to the propagating direction. It seems that sound is "polarized", but we do not sense it: because we can only hear P-wave. (S-wave cannot travel through fluid, e.g. air, water, ...)
Awesome!
great effort....
original way of explanation
THis video answered so many questions I didn't even know I didn't know I had! Thanks!
Came here primarily to learn more about the circularly polarized 5.8GHz FPV camera systems work, but wanted to know about that in general.
Thanks buddy for ur nice explanation with ur demonstration 👍👍👍keep it up
Very educational. Very interesting.
i love it a lot.... fantastic
great video. you managed to make such a confusing topic so much easier.
Great video
Very good presentation... Keep going...
Me likey the attitude......now thats ....COOL👍
Finally, got every single of my doubts cleared.
nice video! and great explanation
Thanks for the Clear Video :)
This was a really nice video. East to understand:
This is great, thanks
Really loved it thank you so much❤
Interesting! ❤
Amazing sir
Amazing !!! Thankss
This is an amazing video! Thank you so much!! :)
wow... really good.

My left ear learnt a lot about circular polarisation. My right one, not so much.
cool video

This is extremely interesting!!!
the best was the one black eye, when u close ur eye :D
good way of explaining
my right ear give you thumb down,cause you don't treat him equally。
The Mantis Shrimp eyes... :o
"My left ear....." - it was so interesting that I didn't even notice that is was shifted to the left. Someone look for a content and someone to find what's wrong.
Nice Explanation.... wanted to know if Circularly and linearly polarized light both from the same source have equal intensity?
Any advice before watching 👀,looks like I need one...
If u teach Physics like this...I would have left my dream of becoming a doctor long ago
Very helpful. Thank you.
Wow! I was really astounded when he span the third sheet infront of the dimmed lamp, and it made it brighter! Almost seems to defy physics!
+Dan Coulson Welcome to quantum mechanics
yeah quantum mechanics defy physics lmao, but this absolutely didn't
The sound is only to the gauche its very asmr thanks you very fascinating
you are goood, brabooooooo.
well explained Sir
Quality explaination
No frills. straight up science!
oh great explanation. thanks
awesome! thank you!
dude ur awesome

Nice trick at 1:45. I assume that you put a circular polarizer in front of the camera to achieve that effect.
yeahhhahahahahaha that's amazing. it's always exciting for me to wonder and see how the effects observable to us can be transmitted to the camera (and by extension, to other corresponding devices too)
Gold.
nice explanation
awesome
Thank you king

I'd not have thought of Dr. Cox explaining quantum physics to me in a magician (sleight of hand) style.
perfect
super easy explaination
awesome...:):)
So circular polarizers have a bandwidth?
Dang, just when you thought things might be simple...
Thanks!

I didn't understand the mirror trick. Why is one of the lenses black in the mirror and the other one black when he turns to the camera?
Thankyou so much for this very nice video first, for a long time i am looking for what is that at the 4:05 your right hand take down for the 3D glasses, I am really want to know where can buy that plastic (that looks no color one) , cause i am want to make the Circular Polarization. thankyou again !
brilliant , and no poo music , well done that man
very good explanation!

could you tell how polarized glass made?
How does a polarizer rotate the circularization and allow us to observe this change in real-time?
'Heyy we're the Beatles.' Oh lordy
First time I heard that a photon has two electric fields.
very helpful thanks
