Define Lateral Inversion.

Hint: Inversion of images which we see in the mirror is known as lateral inversion.

Complete step by step answer:

Lateral inversion is the real or apparent reversal of left and right. For example, the letter b when laterally inverted becomes the letter d (more or less). It is well-known that a plane mirror causes the apparent lateral inversion of objects.
A mirror reverses a three-dimensional object in the direction perpendicular to the mirror surface. However, for reasons of psychology, we usually perceive the change as a left-right reversal.

For example, your right side is directly opposite you in your mirror image. There is no left-right reversal in that sense. However, you don’t usually notice that your front and back are reversed in the mirror. That means the left-right of the “person” you see in the mirror appear reversed instead.

If you think of letters as two dimensional objects there may be no change perpendicular to the mirror surface, but lateral inversion may still be seen. That is usually explained in terms of how the mirror changes the orientation of the letters relative to the observer.

Additional information:
Inversion of images which we see in the mirror is known as lateral inversion. The up-right image on the mirror and left side objects come right side, this is lateral inversion.
That’s why we see “ambulance” written in lateral inversion, so that when any watches it from the rear view mirror of his vehicle, it seems “ambulance” is written on it.

Note: Lateral inversion is a phenomenon in which left appears to be right and vice versa. It is due to direction that light follows when it strikes a reflecting surface, generally a mirror.
