Lecture on Spherical Mirrors

Spherical mirrors are mirrors whose surfaces form a part of a hollow sphere. The spheres can be made of glass or any polished metal surfaces. There are two types of spherical mirrors: Convex Mirror and Concave Mirror. Convex mirror: If the mirror coating is in the inside of the spherical surface, then the mirror is called a convex mirror. Concave mirror : If the mirror coating is on the outside of the spherical surface, then the mirror is called a concave mirror.
