Wave Nature of Light

How does light behave when it goes through a double slit?

I really don't understand why this channel has only 44k subscribers. The number should be a lot more. At leat 10 to 15 times more. Really good class. Thank you sir.

More impressive than his knowledge at teaching physics, is the determination with which he cleans his board

[darkdevil]

I wish you did a lecture like this for Quantum Field Theory, I bet it would be amazing!!!!
Thank you for your lectures, they deserve way more attention than they get.

[mateuszwozniak]

I truly appreciate this video! Thank you sir.

Matt's got some mad wave-drawing skills those things are damn neat.

[lukewoodward]

Love your videos so much. They are helping me a ton to study for my physics exams. It truly means a lot that you would go out of your way to help students like me out by posting this content.

[lovelygirl]

Thank you very much. You are really good teacher.I am from Egypt and watch your video s

[jimmy]

What a superstar! Most enlightening 57min of physics of my life!

[greengirl]

How can a human being have it all. He’s smart and a good teacher, has a nice personality AND HANDSOME?

[ittaitumelo]

The best physics Prof. I’ve seen.
Hands down!

[rubickon]

Excellent. Thank you. Can't wait for more material from you.

[MoriahCarinaContreras]

I was suffering in my Optics section until I found your videos!

[shibamchakraborty]

Thanks Professor.
Loves from Bangladesh.

bruh, this guy looks like sherlock from the England series LOL. amazing.

[naturemc]

This fantastic truly amazing beautiful explanation. Thanks again professor

[maskedmarvyl]

I very much appreciate the explanations; however, like most physics professors, he doesn't go through an actual sample equation. It would have been nice if he had done a couple sample equations of different distances and wavelengths of light, so we could really see the nuts and bolts of the math being done. Instead, he gives the formula, and leaves it to the students to employ it. However, as the rest of us viewers aren't there in his class and aren't given homework problems, we can't do that. It would really help the rest of us viewers at home to see at least one sample problem being done with actual figures.

I think around 36:00, he got mixed up in his explanation and equations explaining the speed of light in a vacuum versus speed of light through a material. Also, he neglected to mention in his equation for speed of light in a vacuum that the index of refraction in a vacuum is considered to be 1, and left that off when he did the calculation of speed of light in a vacuum with his frequency (naught) times wavelength (naught), equaling the speed of light in a vacuum.

Sir, please make video on modern physics comprising of (dual nature of matter, radiation, atoms and nuclei)

[searchexpresseti]

Suppose you have two otherwise identical laser beams intersecting at a small prism with one beam 180 degrees out of phase producing total destructive interference. The beams intersect at the prism at a slight angle like an elongated x.

The index of refraction is wavelength dependent but if the waves are totally cancelled in the prism, would the beams exit the prism at same angle as if the beams constructively interfered?

I assume there are no “waves” and thus no detectable wavelength per se while beams are in the glass if there is total destructive interference at that point in space.

Nice videos Prof, cool board needs automated wipers though, I can make that for you hhh

[saskiavanhoutert]

I can understand the lightwaves used in highprogramming with computers, but what about lowprogramming is that also the acquintance. I learned about zero's and one's or nor's and add's by copperwires. Remarks I do like. Kind regards.
