A concave mirror is a spherical mirror whose reflecting surface curves inward and which converges parallel rays of light to a focus.
The working
Definition
A concave mirror is a spherical mirror in which the reflection takes place at the inner, hollow surface that bulges away from the light.
Converging nature
It is a converging mirror because parallel rays falling on it are reflected to meet at its principal focus.
Images formed
Depending on the object position, it can form real and inverted images or a virtual, erect, and enlarged image when the object is within the focus.
Uses
Concave mirrors are used in torches, vehicle headlights, shaving mirrors, and solar cookers as reflectors.
