Answer
1. Spherical mirror : "A mirror which is made from a part of a hollow sphere is called Spherical Mirror.
2. Convex mirror: "A mirror made by silvering the inner surface such that reflection takes place from the bulging surface" is called Convex Mirror. Centre of curvature is towards the silvered surface.
3. Concave mirror : "A mirror made by silvering the outer or the bulging surface such that the reflection takes place from the concave surface." Centre of curvature is towards the reflecting surface.
