The shapes of the three parts of the special mirror are:
(a) Convex mirror at the top as head size is diminished.
A convex mirror forms a virtual, erect image which is smaller than the object.
(b) Concave mirror in the middle as the body size is enlarged.
Only a concave mirror is capable of producing a virtual, enlarged image when the object is placed between the pole and focal length.
(c) Plane mirror at the bottom as the size of legs are same.
A plane mirror always forms a virtual an image same size as the object.
