The centre of the reflecting surface of a mirror is called the Pole(P). It lies ON the mirror. This is different from the Centre of curvature(R). Each spherical mirror forms a part of an imaginary circle. The centre of this circle is called Centre of curvature. It DOES NOT lie on the mirror.
WebConcave, convex, focal point F, and focal length f have the same meanings as before, except each measurement is made from the center of the lens instead of the surface of the mirror.
