Question

GLASS SLAB : a) Trace the course of different rays of light refracting through a rectangular glass slab at different angles of incidence= 0, any other angle i . b) Mark the angles of incidence, refraction and emergence. c) Mark and define lateral displacement in each case.

Answer 1

Answer:

In case of a glass slab, the incident ray is parallel to the emergent ray, that means the angle of incidence is equal to the angle of emergence. The explanation is as follows: When a ray of light is incident on the surface of the glass slab, it undergoes refraction.
