➡️The center of sphere of which mirror is a part. It is denoted by 'C'

Radius of Curvature

➡️Radius of Sphere of which mirror is a part.

Principle Axis

➡️A line drawn normal to the mirror.

Principle Focus

➡️Point on the principle Axis which the incident Ray after reflection meets(in case of concave mirror)and appear to meet(in case of convex mirror)

Focal length

➡️It is denoted by'f'

➡️ The distance between pole and principle Focus is known as Focal length

➡️ The focul length is half that of the radius

Aperture

➡️It is the diameter of the reflecting surface of the mirror

➡️It is the part of the mirror exposed to light
