I very much enjoyed this explanation of wave plates, until you got to the middle, and started to use expressions and terms you assumed your audience was already familiar with, without explaining them. This is the most common mistake mathematicians and physics professors make: they assume their students or the viewer already understands the math and physical principles involved, and teach the subject as if it's a refresher course, not a new concept whose math terms the student is not familiar with.
^ I love this comment. You are 100% correct, this is the most common disease afflicting educators in the physical and mathematical sciences. I am open to thoughts on how it might be cured. One thing I am considering is moving away from cumulative course-style playlists and to more standalone videos where I assume only very basic familiarity with material. Thanks for adding value to this channel :)
I'm sorry, I think there is a point from 4:00 onwards where you assume that up with a lower refractive index there is a lower frequency associated with them, when in reality they are inversely proportional so lower frequency indicates a higher refractive index. If you meant something else I’m sorry for this comment
I thought the wave along the slow axis just gets delayed relative to the one along the fast axis, it is not clear to me why it would change wavelength.
Great video! I have a question about the notation. One time you use an "i" for the imaginary number, but you use a "j" if it is in the exponent. Since I am not an American I am curious if this is standard in your country. Greetings from Austria!

@@JordanEdmundsEECS I think your explanation was clear. To listen such lecture, one should take effort to learn instead of looking for spoon feeding.

Very intuitive lecture. Expecting more.
Nice video.. This is very useful for my research about quantum state tomography.

At the 00:59, I wanna know which HW (decribed by Jones Matrix) can rotate the x-hat to y-hat. Thank you so much!
Thank you so much! I figure it out! Thank you for your sharing!
Great video! thank you so much
Great video!

Sorry for the confusion, as an electrical engineer I use i and j interchangeably for the imaginary number (sqrt(-1)). There is no difference.
wow, this is a great video.
Sir what is Jones Matrix Eigen analysis and how it measures the DGD.
