- A spherical mirror is a mirror whose reflecting surface is a part of a hollow sphere of glass.
- One side of the mirror is well polished and reflecting, and another side of the mirror is opaque (often painted red).
- Spherical mirrors are of two types - Convex mirror, and Concave mirror.
- The image formed by the spherical mirrors depends on the position of the object.

\(⇒ f = \frac{R}{2}\)
⇒ R = 2f
