How do I find index of refraction if I have the incident angle and refraction angle?

Answer 1

Use snell's law. You have to have both indexes of refraction.

Answer 2

what do you mean by both indexes of refection? I put a lazer beam through water.

Answer 3

On side is air, one side is water.

Answer 4

take a look at Snell's Law

N1 SinTheta1=N2 SinTheta2 right?

Answer 5

and i`m trying to find n2 right?

Answer 6

Yes, if N2 is index of water.

Answer 7

Thanks so much :)
