A spherical mirror is a reflective surface formed by cutting a section from a spherical shell. There are two types: concave mirrors, which curve inward like the inner surface of a sphere, and convex mirrors, which curve outward like the outer surface. The reflecting surface of a spherical mirror is characterized by its curvature, defined by the radius of the sphere from which it is derived. The center of this sphere is the mirror’s vertex. Understanding the curvature is essential, as it influences the mirror’s reflective properties, image formation, and the behavior of light rays upon reflection.
