17. Polarization, Polarizer

MIT 8.03SC Physics III: Vibrations and Waves, Fall 2016
Instructor: Yen-Jie Lee

Prof. Lee discusses the concept of linearly, circularly and elliptical polarized waves. He focuses on the mathematical description of polarized waves. He also shows the way to produce polarized light using a polarizer in class.

This is the most enjoyable lecture I’ve watched

[abdshbli]

I love the systematic way of thinking, it's the first time done in 8.03, we love to see more.

Wow. Lol. I’m very impressed that elliptical polarization is explained using the transformation of circular polarization. Because I simply memorized them in the case of elliptical polarization.
I really like this way to think about and explain something. Lol

These are great. Great lecturer, full on enthusiasm. I've gone through all these so far.

But I got slightly lost here, What is "peak position" or "peak value" at 8.10
- couldn't find in text (think its something obvious I missed)

Sir, I have one doubt. In the demonstration of vertically polarized light and its filtration with vertically placed conducting rods. There are air gaps between the rods. So, some light which coming as vertically polarized one should escape through the air gaps. But on the screen, it is snowing as totally filtered or blocked by the rods, how? Some light should escape through the gaps. Is it not? How the demonstration shown is correct?

[haah]

how does the boundary membrane remain unbroken during total internal reflection?

If you Google you will see that Snel's Law is a matter of perspective, and not a hard physical law.
edit: this does not apply to total internal reflection. I think.
