omg thankyou so much!! :)
-
u saved my ass
-
correction, so it looks like v=c (times) n
-
in order to get V by itself, why cant you multiply, from n=c/v, c on both sides to get v by itself? so the formula would look like v=c (times) v?
-
jesus... significant digits please lol
-
hello
I have a question, how do you find the index of refraction if the incident and refracted angles are given? thx
-
how do you make these videos?
-
Index of refraction is always greater than 1. Otherwise we would violated law of physics. But,using metamaterials it is theoretically possible to control index of refraction. Metamaterials shows bizzare optic properties as negative index of refraction and reverse Doppler effect.

is there any reason not using Material / Vacuum to be N?
1 = Vacuum 0.7518 = Water <--something like this

Use Snell's Law: ni * (sin i) = nr * (sin r)

how do you find V if u dont know it
Aqquatick 2 years ago
You can use the formula n = c / v. And the value for n (the index of refraction) is either looked up in a book or determined experimentally.
Hope that helps,
D.O.
