Definition of a Concave Mirror

A concave mirror is a spherical mirror, which has a reflecting surface, dented inwards. Concave mirrors reflect and focus incoming light rays (parallel) at a point, called the focus point. Depending on the distance of an object from the reflecting surface, different types of images are formed. Concave mirrors are also called converging mirrors since light rays converge after reflection at concave mirrors.

Image Formation By Concave Mirror

By changing the position of the object from the concave mirror, different types of images can be formed. Different types of images are formed when the object is placed:

• At the infinity
• Beyond the center of curvature
• At the center of curvature
• Between the center of curvature and principal focus
• At the principal focus
• Between the principal focus and pole
