WebFocus is defined as the point through which the reflected light rays pass (or appear to pass) when incident light rays are parallel to the principal axis. It is located at the midpoint of … WebA spherical mirror has a radius of curvature R and a focal length f = R/2. The focal length f is the distance between the focus and the surface of the mirror. The figure on the right compares a parabolic and a concave spherical surface with the same focal length f. Near the symmetry axis or optical axis the curves are nearly identical.
