Question

A man standing in front of a special mirror finds his image having a very small head, a fat body and legs of normal size. What is the shape of:

(a) top part of the mirror?
(b) middle part of the mirror?
(c) bottom part of the mirror?
Give reasons for your choice.

Answer 1

A man standing extremely close in front of a special mirror finds his image having a very small head, a fat body but legs of similar size. Hence,

(a) the top part of the mirror is convex, as it forms virtual, erect and small-sized image.
(b) the middle of the mirror is concave, as it forms virtual, erect and large-sized image.
(c) the bottom of the mirror is a plane mirror, as it forms virtual, erect and image of the same size as the object.
