- An illustration of circular polarization, made in Blender.
You could think of this as the workings of a quarter wave plate. If the first resultant wave entered the plate and the optic axis whas parallell to Ez, then the (red) z-component would be retarded by a quarter wavelength and the (blue) y-axis would stay the same. The linearly polarized first resultant wave would then turn into the circularly polarized second resultant wave. - Наука та технологія
2 hours of lecture in 2 mins :). power of visuals. Thanks a lot
2 hours? It was 4 years of undergraduate hahah
This is just perfect. So hard to represent circular polarization in your mind without animation.
You just explained me a chapter in 1 minute 36 seconds .. you are awesome !
this is and you are awesome! i really couldnt imagine how circular polarization looks like and you really helped me out :)
We have some amazing learning tools now that we are so blessed. Imagine visualizing this as recently as the 90s. Insane. People had to go read books in libraries and it barely made sense to a lot of people and some of them lost interest in physics because such a beautiful thing was so hard to explain. The ones that understood went to to love physics, the ones that didn't just hated it.
To understand this you would pull you towards physics , but all reliable maths stand their own ground.
This is the best demonstration for circularly polarized light I found ever.
Totally awesome! I am glad i watched this video from the beginning, instead of trying to picture this process in my head for probably hours!
very simple but clear demo. That saves time and is very efficient. Thanks uploader!
I'm insulted that only 50K(+) people have seen this video! It is applicable in so many mathematical applications is just not fear!
Very good explanation and graphic. Good job.
A big thank you! Excellent visualization of the polarization concept. I will show this video to my physical chemistry students.
Wow, I finally understand how my RHCP and LHCP antennas work. All it took was a simple representation. Thanks for putting this together! Awesome stuff.
First video that immediately helped me with understanding of this concept. Thank you!
This was a hell of a lot easier than I thought.
Thanks!
I wasted my time going from one website to other but couldn't understand what was the basic ....but this video was ultimate..within 2min i got complete overview thanks .. :)
Short and concise, precisely what I needed. Thanks!
Great video. Had some trouble visualizing a circular polarization, but now it's pretty clear. Thanks a lot.
Truly excellent. Simple and concise. Nice work showing Linear polarized first too.
No other video can reveal the mystery of circularly polarization more than that... Expecting more more more visualising video from u sir...We re waiting
Nice work.
I often have wondered how computers and computer animation, specifically, has improved education. This is a good example of how it has made it better. The cost of making this video is so much less than it was 20 years ago.
As trivia, I note the thumbs up to down ratio is about 80x.
You're the best! This just made all the concepts come together! Thank you:)
#Niggaaaaaa
WOW, I couldn't get anything from images in textbook, this is cool way. Thank you. Keep up sir.
Best video for polarisation
this one just saved me !
I have no words to express
Awesome animation! Very helpful for understanding electromagnetic waves! :)
This video is a life saver, thank you 💙.
@mardukbp Thank you! I am still looking into animation based more on equations (seems tricky!), but as far as these basic animations go Blender works great. I accomplished this animation with basic keyframe-animation (rotate, scale and position) so anything on that topic would give you a similar result.
very useful video thanks, it is way easier to understand about circle polarization in comparison with lecture slides I read!
Excellent concise visualization!
This is very good animation, thanks!
Great animation! This was perfect, thanks!
Great presentation in less time..🔥🔥🔥
Thanks u very much 👍
This is excellent. Thanks.
FANTASTIC!
Really helpful. Thank you so much for this video.
this is fantastic.. my concept is clear now thanks
Really great visualization! thanks
Thank you, this has made my homework a lot easier :)
Thank you! I will show it to my students!
awesome, best visualisation. Thanks
Great..got a clear image of polarization. ..thanks a lot
Thank you for the Animation!
thank you for the video! it helps a lot
So Well explained. Thanks!
Woww. This is really beautiful
that was so clear, thanks!
Sweet work man!
Great!! Thanks, very useful to explain polarization to my students. But it would be even better if an example of elliptical polarization has been included.
amazing demonstration
Thank u so much for this!! So helpful
Thanks!
Heard this before and don't understand what it is about till today
A very good 3D animation. I deal with photoelasticity and this animation is very good for explaining this subject.
Excellent video...thanks!!
Awesome ....loved it.thanx
Excellent animation
Love this visualization. Now for a way to measure the polarization. Seems simple but ? Also, wonder if there is some sort of variable phasing system, so the phase could be fine tuned ? So far I have only used coax but perhaps there are other physical methods ? A turnstile is a good practice antenna.
Very good. I like it.
Wow! How easily you make it look.
Awesome video for an intuitive view.
maaaan thank you so much. finally i know how it works
Beautiful
Very useful, many thanks
this is an awesome video
Very nice !
fantastic video.
thank you great explanations
Super happening brother 👍👍
Exllent illustration..
Very good video, thanks. keep up the good job =)
you r the best man ....
Thank you so much!
this is so awesome. sheds so much 'light'. btw, how did you create this animation?
Awesome dear ❤️Thank you 😊
Wonderful.
Helpful Animation
This is just so very very good. Try getting the same intuition with a qualitative description like the ones in entry level university physics books - it's so confusing. And for me the mathematical explanation is no good either unless I can connect it with a visualization like this, the math simply doesn't "show" me the rotation as intuitively as this does (I am sure lots of people will claim that they "see" it already from the mathematical superposition of the waves, I just don't, apparently). THANKS!
beautiful.... thanks
Hats off !!!
Awesome !
scholarly explained well :0
great video for the beginners
Great visualizing I have a picture now
great animations thankyou sir..........
很直观也很详细，感谢上传！
By the way, can I upload this video to some website in mainland China? Cause there's some problems for many people to use UA-cam. If I may, I'll notice where this video comes from. Thanks a lot.
Of course! I approve of any non-commercial use.
Great video!!! may I suggest to do the same with linear polarization? that'd be great too!
Very nice
excelent video.!!!!
Good animation
Thank you for the quick reply Ruff.
Just a question: the vibration planes of the single photons are extremely variable in normal light. Linear polarizers permit the passage of one single direction at time. Are the single vibration planes of normal (e.g., solar) light the result of the magnetic and electric fields (e.g., the first green vector shown in your video)?
A second question: how do circular polarizers work? Do they allow a retardation of the electric field so that it is slowed of 1/4 lambda compared to the magnetic field? If you have any link or document explaining in detail how it is possible to obtain circular polarizers I would be grateful if you can share it.
cheers.
Small video helps great👍
Question....if a round. light source travels through glass double glazing but reflects a different reflection on to a wall is that circular polarization
I think the video is precise to the point. If it feels that it is adding electric and magnetic components than it is observer's mistake.
Thanks!
awesome
Thank you!!!!!
Beautifully done! And, 3D theater movies are accomplished by two projectors, each projecting the movie in circular polarization, but each in opposite directions. The glasses you wear disect each projection using a combination of polarizing filters and quarter wave filters. en.wikipedia.org/wiki/Polarized_3D_system
Am I right in saying that circular polarization is simply a vertical wave and horizontal wave with the release of the horizontal being timed, and that timing is what determines LH or RH polarization?
oohhhhhh it all makes sense now
I owe you🖤💯
