Hint
The ray diagram shows the path of light as it passes through a prism. The angles marked in the diagram are , , , , and . The angle of incidence () is the angle between the incident ray and the normal to the surface of the prism. The angle of emergence () is the angle between the emergent ray and the normal to the surface of the prism. The angle of deviation () is the angle between the incident ray and the emergent ray. The angle of refraction () is the angle between the refracted ray and the normal to the surface of the prism. The angle of reflection () is the angle between the reflected ray and the normal to the surface of the prism. The correct answer is (c) , and .
