Expert Answer:

Magnification produced by a spherical mirror gives the relative extent to which the image of an object is magnified with respect to the object size. It is expressed as the ratio of the height of the image to the height of the object. It is usually represented by the letter m. If h is the height of the object and h ? is the height of the image, then the magnification m produced by a spherical mirror is given by

m = Height of Image (h ') / Height of Object (h) = h ' / h

The magnification m is also related to the object distance (u) and image distance (v). It can be expressed as:

Magnification (m) = h '/h = -v/u
