उत्तर
Lateral Inversion : Inter change of sides between the object and its image is called Lateral Inversion.
It means image formed behind the mirror is as far behind the mirror as object is in front of it.
i.e. distance of M = dist of M in distance of O in front of mirror = distance of O image, and so on.
