Solve the following questions:
Question I: A light ray strikes this material (from air) at an angle of 33.1° with respect to the normal of the surface. Calculate the angle of the reflected ray?
Question II: Calculate the angle of the refracted ray?
Question III: Assume now that the light ray exits the material. It strikes the material-air boundary at an angle of 33.1° with respect to the normal. What is the angle of the refracted ray?
