Draw a labeled ray diagram to show the path of a ray of light incident obliquely on one face of a glass slab.

Open in App

Solution

The angle of incidence is equal to the angle of emergence for a light ray incident obliquely on a glass slab ie $i = e$
Hence the emergent ray is parallel to the incident ray
Given below is a systematic diagram for the path of a light incident obliquely on a glass slab.
