Question

List some characteristics of a plane mirror.

Answer 1

Hint:Some of the common characteristics of plane mirror are the formation of virtual image, apparent right-left image reversal also known as lateral inversion, upright image formation, same image distance and object distance, same size of the image as that of the object.

Complete step by step answer:
The common characteristics of plane mirror are:
-It forms a virtual image: the image formed by a plane mirror is due to the virtual intersection of the rays of the light behind the mirror i.e. the race does not actually pass through the plane mirror.
-Apparent left right image reversal: For a plane mirror left appears as the right and vice versa i.e. the reversal in right and left side of the image takes place .This phenomenon is referred to as Lateral Inversion.
-It forms an upright image: For a plane mirror the image is formed behind the mirror and it is upright.
-The distance of the object from the plane mirror is the same as the distance of the image from the plane mirror.
-The size of the image formed by a plane mirror is the same as the size of the object placed in front of it i.e. the magnification of a plane mirror is 1.

Note: Images formed by plane mirrors are virtual, upright, left-right reversed, the same distance from the mirror as the object's distance, and the same size as the object. 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.
