Circular Polarization

[@PeteBeast]

my left ear is thankful for this video!

[@jessesinger4790]

oh good, my earphones aren't broken

[@InterMinder7ham0]

:D

[@Motivic167]

Unfortunately, my left side of my headphones don't work :(.

And my right😂

[@naurseakart1190]

@@ammarraza1956 due to overuse, I hear less by a factor

[@NaveenKSomasundaram]

That's brilliant. A not so intuitive phenomenon explained with such simplicity.

[@dirm12]

Finally a video that makes sense of this phenomenon, and doesn't just say 'it's another type of polarisation'.

[@alexlistigovers253]

The connect the string analogy really helped me wrap my head around the vector motion, thanks!

[@baraskparas]

Great presentation. Informative and interesting. Some subtle humour appreciated! Thanks.

[@annalenasegler]

I love it! Explained in such an easy way!

[@OnTheAir]

I particularly like the sliding white E cardboard wave to show 90 deg. phase shift. Well done!

[@melody3741]

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.

[@vaibhavsaxena231]

That was one nice presentation !! Congrats for the good work !!!

[@geoablesd188]

You're so weird I love it!! Keep the vids coming

[@exoticpropulsion8175]

Most professional video lesson I have ever seen on polarization wave shape!

[@BirdyMac3g]

simple explanation, great visual. u the man

[@lambda4931]

Best explanation online! Thank you one million times

[@cyberlightbeing]

Absolutely brilliant!

[@Sam_Chintapalli]

Woow ...... Just amazing...... ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️

[@rahulvarma3004]

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!!!!!

[@chetankumar3964]

excellent demonstration you make to understand the polarization ..thanx

[@megakiller999]

That was absolutely awesome! thank you!

[@muniswamy100]

WoW, Saved a Ton of reading with this brilliant video

[@ramkishorsah8554]

Thanks buddy for ur nice explanation with ur demonstration 👍👍👍keep it up

[@andyzysraul]

Wow, very impressive explanation.

[@MovieMongerHZ]

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.

[@noobtextwritergamer]

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

[@jyoti9426]

Best explaination yet 👌👌

[@vivekanandsahoo5181]

Wow Amazing video ever... I like it

[@akinoz]

This would be one of best explanations ever. Thanks professor.

[@cchollands]

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.

[@Singingmom320]

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.

[@mibo747]

IDEAL presentation!

[@maxheadrom3088]

Awesome!

[@abubakrbinumar9635]

great effort.... original way of explanation

[@power-max]

THis video answered so many questions I didn't even know I didn't know I had! Thanks!

[@power-max]

Came here primarily to learn more about the circularly polarized 5.8GHz FPV camera systems work, but wanted to know about that in general.

[@gagebarry6938]

Explained so well!

[@ananthakrishnank3208]

Brilliantly explained!

[@Loomyer]

Great video

[@lironsifado]

you changed my life

[@JaeV-xs7vz]

great video. you managed to make such a confusing topic so much easier.

[@rudheeshrk]

Very good presentation... Keep going...

[@bharathreddygudibandi492]

i love it a lot.... fantastic

[@maskedmarvyl4774]

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.

[@NikitaVerma-the-one-and-only]

This is an amazing video! Thank you so much!! :)

[@TheBishopSSR]

Great informative video. Was the sound for it polarized as well? My left ear is receiving one component only ;)

[@haoli6628]

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, ...)

[@ikemoon127]

Very educational. Very interesting.

[@jessesinger4790]

This is great, thanks

[@tilakpawar979]

This was a really nice video. East to understand:

[@DANGJOS]

nice video! and great explanation

[@dancoulson6579]

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!

[@9181shreyasbhatt]

+Dan Coulson Welcome to quantum mechanics

[@Trec-u]

yeah quantum mechanics defy physics lmao, but this absolutely didn't

[@anupamamandal6960]

Nice Explanation.... wanted to know if Circularly and linearly polarized light both from the same source have equal intensity?

[@naurseakart1190]

Finally, got every single of my doubts cleared.

[@ruzzellcrowe9352]

The Mantis Shrimp eyes... :o

[@0Bato]

The sound is only to the gauche its very asmr thanks you very fascinating

[@Khwartz]

Thanks for the Clear Video :)

[@Nusantara999]

Interesting! ❤

[@timoteo6515]

you are goood, brabooooooo.

[@GseichtsG]

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?

[@kishfoo]

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.

[@FlorenciaCSalas]

Amazing !!! Thankss

[@anaeem86]

Me likey the attitude......now thats ....COOL👍

[@KISHORENEDUMARAN]

cool video

[@noor-ul-ain3779]

Really loved it thank you so much❤

wow... really good.

[@AmartyaGhoshee]

This is extremely interesting!!!

my right ear give you thumb down，cause you don't treat him equally。

[@andyowen3685]

No frills. straight up science!

[@akashengbt]

good way of explaining

[@Ricky23289]

the best was the one black eye, when u close ur eye :D

[@navyansh5168]

Amazing sir

[@expchrist]

Nice trick at 1:45. I assume that you put a circular polarizer in front of the camera to achieve that effect.

[@yash1152]

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)

[@Tadesan]

So circular polarizers have a bandwidth? Dang, just when you thought things might be simple... Thanks!

[@manideepreddyenugala4097]

Any advice before watching 👀,looks like I need one...

[@brightbit1965]

Gold.

[@alinakorbut2452]

awesome! thank you!

[@sirpatmcc]

Very helpful. Thank you.

[@rendermanpro]

"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.

[@chris24hdez]

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?

[@sirguythe7th]

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.

'Heyy we're the Beatles.' Oh lordy

[@mahmoudgharib9223]

awesome

[@jasonselph6968]

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)

[@anon1123a]

perfect

[@nitinmishra7100]

awesome...:):)

[@SqnLdrVinutha]

oh great explanation. thanks

[@TheRodiscumbag]

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

[@edis9493]

How does a polarizer rotate the circularization and allow us to observe this change in real-time?

[@ravindergoyat4316]

Quality explaination

[@silentjoe4745]

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.

[@jameshuang7982]

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 !

[@nowonmetube]

I'd not have thought of Dr. Cox explaining quantum physics to me in a magician (sleight of hand) style.

[@alba5580]

All my life, I have been taught that light is made of an electric field with a magnetic field (perpendicular to each other). But in this video it was explained that polarized linear light is made out of two perpendicular electric fields (that sum up to a vector in one direction), does it still have a magnetic field?

[@benni_crafter4931]

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?

[@StevenRobertsJr]

The Mantis Shrimp brought me here

[@rathanm4397]

thought my headphones on the right got broken. .hhaha

[@xkriolox]

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?

[@sandeepsekharpk]

nice explanation

[@4DRC_]

There are x and y components of the e field but are there also x and y components of the b field, it's net force perpendicular to the e field's net force?

[@fishmodem]

1:18 eyyy we're the beatles

[@ThisisKrishnakumar]

Why do we need Circular polarization of light for Photoelastic study of Stresses?

[@pameslinkoln]

Stress causes circular polarization because it creates a different index of refraction (speed of light) along the axis of stress

[@madhvipandey1708]

well explained Sir
