Spherical Mirrors

A spherical mirror is a mirror which has been cut out of a spherical surface. 

There are two kinds of spherical mirrors:

  1. Convex Mirror
  2. Concave Mirror

Concave Mirror

Concave mirrors are also called converging mirrors, because in these types of mirrors, light rays converge at a point after impact and reflect back from the reflective surface of the mirror.

Convex Mirror

The convex mirror has a reflective surface that is curved outward. Regardless of the distance between the subject and the mirrors, these mirrors are "always" virtual, upright and reduced.
