The image formed by an object placed in front of a plane mirror is (a) at distance equal to distance between object and the plane mirror.
By applying the laws of reflection to a plane mirror, we find that a virtual image is formed behind the mirror, at a point which is at a distance behind the mirror, that equals the distance between the object and the mirror. This virtual image is only formed when we consider the object to be a real object, that is, the light rays actually emerge from it.
