Lateral inversion: Sideways reversal of the image is known as lateral inversion. If we stand before a plane mirror and move our right hand, our image appears to move its left hand. Infact, our entire image is reversed sideways.
Fig. Lateral inversion before a mirror
Cause of lateral inversion: In a plane mirror, the image is as far behind the mirror as the object is in front of it and that the front of the image and the front of the object face each other. This is the cause of lateral inversion in plane mirror.
The laterally inverted image of the word LEFT is as shown in the figure above.
The images of symmetrical letters like A, H, I, M, O, T, U, V, W, X, Y, 8 are not affected by lateral inversion.
