How do I find index of refraction if I have the incident angle and refraction angle?
Use snell's law. You have to have both indexes of refraction.
what do you mean by both indexes of refection? I put a lazer beam through water.
On side is air, one side is water.
take a look at Snell's Law
N1 SinTheta1=N2 SinTheta2 right?
