Detailed Solution

A point source of light is placed in front of a plane mirror all the reflected rays meet at a point when produce backward.
Behind the mirror, the image of a point source in a plane mirror will be a virtual point image. When produced backwards, the reflected rays should meet at this point. A light source that emits highly directional light radiations into the environment that are typically concentrated on a single point is referred to as a point source of light.
