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.

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. Hence,

(a) the top part of the mirror where he finds his very small head is a convex mirror, as it forms a virtual, erect, and small-sized image.

(b) the middle part of the mirror where he finds his fat body is a concave mirror, as it forms a virtual, erect, and large-sized image.

(c) the bottom part of the mirror where he finds his legs of normal size is a plane mirror, as it forms a virtual, erect, and image of the same size as the object.

Explanation

The order of the special mirror (made up of three types of mirrors), from top to downwards is:

1. A convex mirror  -  always forms an image smaller than the object. 

2. A concave mirror - forms an image larger than the object.

3. A plane mirror - always forms an image similar to the size of the object.
