Question

Which of the following letters does not show lateral inversion?
A. $M$
B. $N$
C. $I$
D. $A$

Answer 1

Hint:The lateral inversion is a type of image formed in a plane mirror. When we put a letter or an alphabet in front of a plane mirror, the image inverts. This is called lateral inversion. For lateral inversion, the size of the image is the same as the size of the object. This change is only done laterally, not vertically.

Complete answer:
Lateral inversion is defined by the phenomenon in which the image is inverted laterally w.r.t the object. The lateral inversion only occurs laterally, not vertically. The left side and right side of a symmetrical object are the same, that’s why the lateral inversion does not observe.

The letters \[A,H,I,M,O,T,U,V,W,X\] are symmetrical. And the letters \[B,C,D,E,F,G,J,K,L,N,P,Q,R,S,Y,Z\] are non-symmetrical; so the lateral inversion can be observed.So, by considering the given options we can say that \[A,M,I\] do not show the lateral inversion.

Hence, the correct answer is options A,C and D.

Note:Let consider a diagram,

According to the diagram, the point $P$ on the letter $F$ and the image is formed in point $P'$ Since the distances of the points on the object from the mirror are equal to that on the image from the mirror $B$ and the eyes at point $A$ . Hence, a lateral inversion occurs. Thus the inverted image of the letter $F$ is shown.
