The refractive index of a transparent material can be determined bymeasuring the critical angle when the solid is in air.
a) If c= 40.2° what is the index of refraction of thematerial?
b)A light ray strikes this material (from air) at an angle of 32.5°with respect to the normal of the surface. Calculate the angle ofthe reflected ray (in degrees).
c)Calculate the angle of the refracted ray (in degrees).
d)Assume now that the light ray exits the material. It strikes thematerial-air boundary at an angle of 32.5° with respect to thenormal. What is the angle of the refracted ray?
