That is why MIT is the No 1 university. Thank you, professor, you clear out my confusion at all. No one explains in such a way.

[@roonilwazlib8137]

Great explanation

[@maskedmarvyl4774]

I have watched every video I can find on wave plates, and read every article I can find explaining them, and not one of them explains what is physically happening inside the medium (other than mentioning the different indexes of refraction for differently oriented polarized light). I want to understand what is happening at the atomic level to alter the phase of the polarized light, and no-one has yet to describe that.

[@zodensu9044]

me neither, bro. I am now very confuse and curious about what physically happend wenn light transmittance the half wave plate.

[@ankitthakurankit4764]

maybe the nswer no one knows why dont you dicover it yourself using your urrent knowledge and some experiments

[@non-inertialobserver946]

You should first understand how an optical medium changes the speed of light waves (what is the origin of the index of refraction?). There is a good chapter about this in the first volume of Feynman's lectures on physics, which you can find for free on the internet.

@@non-inertialobserver946 , Thank you, I'll look it up.

Thank you very much! ^^!

Why do you wear a watch and ring? but no safety glass?

It is just a HeNe! Probably 20mW only.
