A spherical mirror is a mirror that has the shape of a piece cut out of a spherical surface. There are two types of spherical mirrors: concave mirror and convex mirror.
Types of Spherical Mirrors:
1. Concave mirror (converging mirror)
2. Convex mirror (diverging mirror)
Terms in Spherical Mirrors:
Pole (P): The center of the mirror surface.
Centre of Curvature (C): The center of the sphere from which the mirror is a part.
Radius of Curvature (R): The distance between the pole and the center of curvature.
Principal Focus (F): The point where parallel rays converge or appear to diverge.
Focal Length (f): The distance between the pole and the focus.
