Relative Angles of light rays? - index.of found jpg
The following figure shows a ray of light from one material to another, then another. Given the relative angle of the light rays in the figure, which of the following best describes the relative size indices of refraction?

A) n2> n3> n1
B) n2> n1> N3
C) N3> n1> n2
D) n1> n2> n3
Imagine a beam in a material of unknown refractive index of the incident at an interface with a material of refractive index of 1.07. It turns out that the critical angle of 46.71 degrees. What is the refractive index of the material?

B. angle greater than normal in 3, the longest side to 1 at least 2
Critical Angle = arcsin (N2/N1), where N2 is the least of IR --
2 = 1.07, n1 = n2/sin (46.71 degrees) = 1.47
