1- A- The refractive index of a transparent material can be determined by measuring the critical angle when the solid is in air. If θc= 41.6° what is the index of refraction of the material?
B- A light ray strikes this material (from air) at an angle of 31.8° with respect to the normal of the surface. Calculate the angle of the 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
the material-air boundary at an angle of 31.8° with respect to the
normal. What is the angle of the refracted ray?
