The figure below shows the refraction and emergence of a ray of light incident on a rectangular glass slab. Copy the diagram and mark the lateral displacement of the incident ray. Name the two factors on which the lateral displacement depends.

(N/A) The lateral displacement depends upon:
$(i)$ The angle of incidence of the incident ray $PQ$ on the face $DC$ of the given glass slab.
$(ii)$ The thickness of the glass slab.
The lateral displacement is defined as the perpendicular distance between the emergent ray and the original path of the incident ray $PQ$ when produced forward.
