n=1.36

~~~~~~~~~~~Angle=15.60 degrees

n=1.73

~~~~~~~~~~~Angle=17.94 degrees

n=1.51

~~~~~~~~~~~Angle=27.71 degrees

n=1.0003

~~~~~~~~~~~Angle=11.08 degrees

n=2.42

~~~~~~~~~~~Angle=13.80 degrees

n=1.95

I solved for all of the angles using Snell's law, but I don't know how to tell if there's no angle of refraction and which substance would reflect the light.

**drwls**, Sunday, March 22, 2009 at 5:46pmThere is no refraction angle (A2) if the sine of the computed angle (using Snell's law) is equal to or greater than 1.

N1 sin A1 = N2 sin A2

sin A2 = (N1/N2) sin A2 < 1

sin A2 < N2/N1;

otherwise there is only total internal reflection
