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?
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.
