Question

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

Options

• All the reflected rays meet at a point when produced backward.

•  Only the reflected rays close to the normal meet at a point when produced backward.

•  Only the reflected rays making a small angle with the mirror meet at a point when produced backward.

• Light of different colours make different images.

Answer 1

All the reflected rays meet at a point when produced backward.

Here, the angle of reflection is equal to the angle of incidence. Therefore, all rays get reflected to converge at a single point to form the point image of the point source.
