Good day, I have this question about using Snell's Law: SinTheta1/SinTheta2 = N2/N1 How can I find SinTheta 1 or 2 or N 1 or N2? The aim is the find an angle at which light going from N1 to N2 materials, like glass and persepex, does not go through but reflects. Anyone know?

You need to know three of the variables to get the fourth.
