Question

Write the expression for the magnification produced by a lens in terms of object distance and image distance.

Answer 1

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 the image"/"Height of the object"`

= `(h')/h`

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

m = `v/u`
