A concave mirror is a type of spherical mirror where the reflecting surface is the inner-curved surface of the sphere. Unlike flat mirrors, concave mirrors have a curved reflective surface. Here are some important terms related to concave mirrors:

Pole (P): The center of the reflecting surface of a spherical mirror.
Centre of curvature ©: The center of the sphere formed by the reflecting part of the mirror. It lies outside the reflecting surface of the mirror.
Radius of curvature ®: The radius of the sphere formed by the reflecting part of the mirror.
Principal axis: The straight line passing through the pole and the center of curvature of the spherical mirror. It is normal to the mirror at its pole.
Principal focus (F): The point on the principal axis where incident rays parallel to the axis converge (or appear to converge) after reflection.
