Question

The sideways reversal of the image by plane mirror is called:
(A) Lateral inversion
(B) Parallax
(C) Optical Illusion
(D) None of these

Answer 1

Hint To answer this question it is required to know the meaning of all the mentioned options. After the description we can find out which will be the specific word to describe the phenomenon mentioned in the question.

Complete step by step answer
We should know that lateral inversion is defined as the sideways reversal of the image’s left and right when compared to that of the object.
Lateral inversion is observed in images formed by the plane mirror.

Hence the correct answer is option A
The phenomenon of lateral inversion describes the situation where in the formation of the image by the plane mirror, the left side of the object appears to become the right side of the image, and the right side appears to become that of the left side of the respective image.

Note To make sure that we do not confuse between the options that are mentioned it is required to know the definition of each of them.
At first let us begin with the definition of Parallax. By parallax we mean the apparent displacement of the object because of the change in the point of view of the observer. The main use of the parallax is that it is used to determine the distance of the objects that are present in the nearby object in the space. This method is known as the stellar parallax or trigonometric parallax.
By optical illusion we mean the occurrence of the illusion because of which we see something different from what the object really is.
