Question

A point source of light is placed in front of a plane mirror.

• A. Only the reflected rays close to the normal meet at a point when produced backward.
• B. All the reflected rays meet at a point when produced backward.
• C. Only the reflected rays making a small angle with the mirror, meet at a point when produced backward.
• D. Light of different colours make different images.

Answer 1

The correct option is B All the reflected rays meet at a point when produced backward.

Plane mirror always forms a virtual image of the real object for all the rays emitted by the object. So, when a point source of light is placed in front of a plane mirror, all the reflected rays met at a point when produced backward.

Option B is correct.
