Where does the center of curvature lie in relation to the reflecting surface of a concave mirror and a convex mirror?

For a concave mirror, the center of curvature lies outside the mirror, along the principal axis, in the direction opposite to the reflective surface. In contrast, for a convex mirror, the center of curvature is also outside the mirror but along the principal axis, in the direction of the reflective surface. The location of the center of curvature is determined by the curvature of the spherical surface from which the mirror is derived. Understanding this relationship helps in defining the geometry of the mirror and is essential for analyzing and predicting the optical behavior of concave and convex mirrors.
