Calculating the Speed of Light in Water - Mr Pauller

This video shows how to calculate the speed of light in water.

This video will be incorporated into my new project which will discuss the science of the formation of plasma when a grape is microwaved!

The circle pie-like thing you did, sure came in handy and made the equation faster and easier to understand.

Simple and beautiful, sir. Thank you.

I'm afraid I don't know what quality the "n" refers to.

Ah. Refractive index.

This is likely an ignorant question…. Does light traveling slower outside a vacuum create a strange or interesting paradox? Suppose a cosmic lottery is held near Sagittarius A and I am on the ISS. Could I know the winning numbers before someone at the bottom of the ocean and buy a ticket there before the lottery even happens there? I can think of some logical (non-physics) reasons why that is not possible. But why? Does the reason have something to do with Einstein’s special relativity claim that viewers’ observations of ‘now’ are equally valid?

Hello sir...
I have calculated how much gravity acts to speed of light in water so I need some help from you that I want to clarify that it is correct so..I need little bit reference from you....
Please sir I can be future if my equation is right

Sir, I have a question... where did you get the 1.33?
a question from a highschool student

[pravinsharma]

why did you do that circle trick it's just soo basic We can simply divide both the sides of the equations by u and multiply by v to get the result .the thing you did will lead your students to mugging us the things
