Seeing you every time in YouTube makes me happy, thanks a lot for such wonderful concepts

Everyone, yes Everyone studying Electrical Engineering, should watch all the 8.02 lectures, which are truly wonderful. I graduated many years ago in the UK, but having watched these lectures recently, at the age of 60, I now understand electromagnetism far better than I ever did. And I have put this knowledge to use in real industrial solutions. Thankyou so much Prof. Lewin.

SIR JUST WANTED TO SAY THAT YOUR VIDEOS ARE A BEACON OF LIGHTS FOR MANY LIKE ME!! THANK YOU

[vaibhavvivek]

Thank you sir! You are truly an inspiration to us aspiring scientists!!!

Hello Sir, I am Hrishikesh Biswas from India. I have few questions on light-

Once light enters in a denser medium it slows down, and when escapes into rarer medium it gets back to a higher velocity.

Q 1. When light hits the interface of a denser or rarer medium, does its velocity change at an instant?
Light instantly gaining or dropping to a different velocity is a conflict to the idea that light can't surpass the speed C. An instant change in velocity would mean that the rate of change of velocity is undefined i.e v2 - v1/0 ms^-2 which seems to be a very contradicting value.

Q 2. Light shifts to a higher velocity after passing into rarer medium. How does light get this extra energy to speed up? Can it be that there are other properties of light that gets compensated for making change in velocity possible as it travels through various media?

Actually this question was in my jee mains 2020(jan)

Dear Dr. Walter Lewin,

Thank you so much for sharing your wisdom with us, Sir.

You are such a great inspiration for millions of poor students like me.

I wish I will become a MIT Professor like You at one day. I knew it is very difficult but not impossible with a dedicated passion, and resilience. Please bless (me and many other students) with your noble heart.

We love you and we are really lucky to have a teacher like you. Take care of your health, Sir <3
