Solution
A concave mirror is made by silvering the outer ( or bulging ) surface of the piece of a hollow sphere such that the reflection takes place from the concave surface.
A convex mirror is made by silvering the inner surface of the piece of a hollow sphere such that the reflection takes place from the outer surface.
