A person is standing at a distance of 2 m from a plane mirror. Now, he moves 1 m away from the mirror. His image will move:

The correct option is C

1m away from the object

1. It is the property of the plane mirror that the object and image distance are at the same distance from the mirror.
2. So after the man moved 1 m away from the present standing position his image will also move 1 m away from the present position.
3. Therefore, the image formed will be 1 m away from the present position of the mirror.

Hence, the correct option is (C).
