(b) In the diagram, mark the angle of incidence (i) and the angle of refraction (r) at the first interface. how is the refractive index of glass related to the angles i and r ? (c) Mark angle of emergence by the letter e. how are the angles i and e related ? (d) Which two rays are parallel to each other ? Name them (e) Indicate in the diagram the lateral displacement between the emergent ray and the incident ray. state one factor that affects the lateral displacement.
