A beam of light in substance 1 (index of refraction = 1.25) has an angle of incidence of 43° at the boundary with substance 2 (index of refraction = 1.62). What is the angle of refraction?
A narrow beam of light is incident from air onto a glass surface with index of refraction 1.56. Find the angle of incidence for which the corresponding angle of refraction is one-half the angle of incidence. Hint: You might want to use the trigonometric identity $\sin 2 \theta=2 \sin \theta \cos \theta$.
