Question

a man stands 3 m in front of a plane mirror and as a wall phone4 m behind in what is the distance between man and the image of the wall it is image of the wall not man ok I don't want wrong answer need explanation also​

Answer 1

Answer: The distance of image from the plane mirror is same as the distance of object (person) from the plane mirror but the image is formed behind the mirror.

∴    v=u=3  m

Thus distance between image and the person        d=u+v=3+3=6  m

Answer 2

Answer:

A plane mirror is a mirror with a flat reflective surface.

For light rays striking a plane mirror, the angle of reflection equals the angle of incidence. The angle of the incidence is the angle between the incident ray and the surface normal.
