State the path after reflection in a spherical mirror when the incident ray passes through the principal focus.

Open in App

Solution

In the case of a concave mirror, the incident ray passing through the principal focus emerges parallel to the principal axis after being reflected by the mirror.

On the other hand in the case of a convex mirror, the incident ray that appears to pass through the principal focus emerges parallel to the principal axis after being reflected by the mirror.
