Answer....

Magnification of a lens →

Magnification of the lens is defined as the ratio of height of the image to that of an object .

It is also defined as the ratio of image distance from the lens to the object distance from the lens.

Formula →

$\boxed{m \: = \frac{h_i}{h_o} = \frac{v}{u} }$

where

$h_i \: = \: height \: of \: image \\ \\ h_o \: = \: height \: of \: object \\ \\ v \: = \: image \: distance \\ \\ u \: = \: object \: distance$
