Find the angle of refraction if there is one. If there isn't, tell which substance reflects the light:

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.
