Reflection and Image Formation by Mirrors
depthome.brooklyn.cuny.edu(f) is given by mirror equation d o d i f 1 1 1 (3) where d o, d i and f are measured from the mirror on the principal axis. The magnification of the image is given by o i o i d d h h m (4) Both relations given in Eq. (2) and (3) hold for concave as well as convex mirrors. Focal length for concave mirror is taken as position and for convex lens ...
