Define linear magnification produced by a spherical mirror. Also,give its relation.

(N/A) Linear magnification $(m)$ produced by a spherical mirror is defined as the ratio of the height of the image $(h^{\prime})$ to the height of the object $(h)$.
Mathematically,it is expressed as:
$m = \frac{\text{height of the image}}{\text{height of the object}} = \frac{h^{\prime}}{h}$
Additionally,it is related to the object distance $(u)$ and image distance $(v)$ as:
$m = \frac{h^{\prime}}{h} = -\frac{v}{u}$
Here,$u$ is the distance of the object from the mirror,and $v$ is the distance of the image from the mirror.
