A man stands in front of a mirror of special shape. He finds that his image has a very small head, a fat body, and legs of normal size. What can we say about the shapes of the three parts of the mirror?

(a) Convex, Concave, Plane

(b) The plane, Concave, Convex

(c) Concave, Convex, Plane

(d) Convex, Plane, Concave

I have been asked this question by my school teacher while I was bunking the class.

My question is taken from Reflection of Light by Spherical Mirrors in chapter Ray Optics and Optical Instruments of Physics – Class 12

Best answer
Right answer is (a) Convex, Concave, Plane

To elaborate: The upper part of the mirror is convex. The middle part of the mirror is concave. The lower part of the mirror is plane. The image formed by a plane mirror will not have any changes, whereas that will not be the case for concave and convex mirrors.
