That drawing of the perpendicular magnetic fields was amazing.
I came to the comments to see if anyone else felt that way. I was amazed
ikr, it was so satisfying for some reason
Yh why aren't more people talking about it
I even tried it myself because it felt so easy and satisfying
@@Marius1708 what soft ware is it
4:52"...sun is shining and it is a beauuuutifullll day")))) here, at my computer I feel your enthusiasm
2:20 "This thing's hot!" I laughed way too hard.
i don’t even take physics but came across the concept of polarization and was intrigued by it and decided to search some videos up. u did a great job at explaining it even for a non physics student. great job!!
I've never experienced a better explanation of polarization. Thanks a ton! This is gold :P Also, I loved the movie theater example.
Just tried to understand this for about an hour, but you made this perfectly clear in less than 4 minutes. Thanks!
Man, been reading a textbook for a week and couldn't grasp this... Your drawings REALLY came in handy, THANK YOU
Thank you for explaining. I'm a masters student and I feel like I understand polarization more than I ever have before lol
Not until u know about the Poincare sphere(corresponds to the Bloch sphere in quantum information science! ) and the rigorous definition of polarization😏
@@joewang4962 bro, I just need to pass the class. LMAO
Loved it it feels so good to just know stuff without te pressure of having to mug it up and write it for tests....this feels the right way of studying
After doing a lot of survey , i finally got something actually qualitative and worthy . Thanks 👍👍
Thank you for all the examples and explanations. It was really helpful that you always questioned "why are we doing this?" and answered it right away, phenomenal.
Wow, I've been trying to find a way of explaining Polarisation regarding fibre optic transmission and multiplexing and this has helped massively.
Brilliant! At last someone has got it through to my brain....... struggled with this for AGES. Thank you very much.
U explained really v well, u r definitely a very good teacher.
Easiest explanation to understand out of all the many textbooks I have read. Thanks!
70 percent of people watching this video didn’t come here because of one quiz question in a class, they came here out of genuine curiosity about how the world works. These are the people you should be employing.
I came here for a visual understanding of an RCP wave
Really satisfying
Thanks
As an IB student struggling in HL physics, this helps so much. Definitely going to do Kahn with IB to help me through.
damn i am doing the same for HL Physics lol
First time I experienced polarised glasses was actually on the lake fishing with my dad. The sun was out, and the glare off the lake was brutal. I was wondering how my dad was trolling the boat around the stumps in the a cove on the lake that I couldn’t hardly see. At one point he gave me his shades and bam, it was a huge difference. I didn’t get to keep them on long as he wanted them back so he could continue avoiding the tree stumps.
Well, I got my first set of polarised shades at the tackle shop dad bought me and those new shades have been sitting at the bottom of that lake for 30 years now as when I bent over the boat to get a fish netted, they fell off.
Aw, great story!!
Fantastic explanation. Both, colloquially and with your drawing skills. Thank you!
this explanation was incredible! thank you so much for taking your time making this video
This is more exciting than I thought. Great explanation!
best ever.....i'll share with my all classmates who are going through the same problem
this was an excellent explanation thank you so much!! feeling happy i understand what polarisation is now!
That was superb, thank you very much for this movie and excellent explanation with simple graphics but hugely informative.
thanks! great video. Really helped me understand what is going on in CD experiments
This is awesome... I've been working with retarder material and this helps me understand the concept of polarisation even more. I on behalf of viewers from years 2024, Thank you very much.
That helps a lot! Thank you so much! Your explanation was so clear.
BEST EXPLANATION VIDEO, so simple and clear.
that was very educative, thank you. keep up the good work
❤
I am so lost currently in my laser and photonics class and this definitely helped a lot
Awesome ! Thanks Khan academy for making such brilliant videos.
Literally a saviour!
Thank you for your clear and precise explanations
Excellent explanations ! Thanks !
Thank you for posting this - you are a most excellent teacher!!!
beautiful explanation...thanks for sharing knowledge
It is the best explanation I ve ever heard and seen. Both informative and interesting
Excellent presentation. Easy to understand, my compliments.
simple but great explanation of circular polarization. that what i was looking for
Wow.. What an awesome explanation! Thank you.
such a beautiful explanation.
thank you so much for your help!
I am watching you from iraq this was Amazing! Thank you so much ❤
Didn't realize 3D glasses worked like that
Amazing explanation. Thank you 🌹
wow thanks dude ! thats what I needed to see
first time i came to know what is polarization. great video
OMG polarization simplified, thank you so much, 2021 anyone?
A Nice explanation. Thank you..
Phase,Twilight,eyes of wisdow,nine ropes,polarized light,crow and declaration between front and back hollow PURPLE
Thanks I totally understood polarization now, it was so messy in my brain :)
Can you also explain with equations? Like matrix calculations. Thanks a lot! :) Your video is awesome!
Extremely informative. Thank u sir.
Amazing video on polarization, thank you so much !
Excellent explanation, thank you very much!
Great explanation! Very clear!
lovely... thanks for such an amazing explanation!
When I was little I always noticed how if I tilted my head far enough the image in the 3D movie got all funky. Now I know why!
Thank you so much finally I understand what is polarization:)
The cinema example was mind blowing thanks!
great explanation.. even i understood ;D
No fantasy animation, just simply and easy to understand ,thanks
great presentation, appreciate it
Awesome explanation of light polarization!
such a good presentation thank you so much!!!
This guy can explain in twenty minutes what takes my prof two hours 😂
this was great, thank you
Thanks for the video. Thank you sir.
man you saved my life. thank you bro
thank you sir the movie theatre example was soo good!!! I feel so glad that I know it now. thank you sir, I loved the explanation..
Thank you so much , I was so confused until I saw the video
dude physics is everywhere !!
great video... really helped me ....thanksss
Damn good explanation. Thanks.
wow...that's amazing, thanks
Most clear thanks for the glasses
Thank you for posting !
Beautiful explanation ✨
Aha, now I'm starting to understand how the 3d on the 3ds works. Looking at the 3ds screen with my polarized sunglasses and slowly rotating it produced the same "colour/brightness filter" as when doing the double/triple polarized lenses experiment that there are loads of video examples of here on YT. Amazing what one can learn with an accessory, some basic explanations, and a curious/investigative mindset. My day has been made!
EDIT: I feel like im missing something though...
Amazing. Lovely video!
Very good; now I want to know how this is accomplished.
One question that I cannot find asked anywhere: Is there an ideal rotation of a circular polarizer camera lens? If so, could I find that point and mark the bezel and just turn it to that every time?
Thanks, helped me a lot. Cleared a doubt
Keep it up sir please make more videos this is very important and useful for us
That was beautiful.
thanks, great explanation
Thanks for the video!
nice explanation! as far as I understood, to get the circular polarization we must have a phase offset between the E and H components, right?
Dude, this video is great, thanks!
GREAT JOB KHAN ACADEMY !
Great! Thanks!!!
As per wave particle duality can electron behaving like wave can show polarization and how?
thank you verey much it helped me ! great
amazing video! very informative
Thank you man! 😊
It helps me a lot thank you
This was fantastic!
this is awesome!
great video, it helped!!
Great explaination
Thank you for such a lucid explanation.
