You can use this program if you want to calculate the angle which a beam of light will make if it goes through two different materials.

Symbols used in this program:
I = angle of incidence
R = angle of refraction
T = angle of reflection
N = a value which is different for all the combinations of materials (and the color of the beam of light)
