Question
Define the magnification of a spherical mirror.
✓
Answer
Magnification (m): The ratio of the size of the image $\left(h^{\prime}\right)$ and the size of the object $(h)$ is called the magnification of the spherical mirror, i.e. $m=\frac{\text { Size of image }\left(h^{\prime}\right)}{\text { Size of object }(h)}$ $\Rightarrow \quad m=\frac{h^{\prime}}{h}=-\frac{v}{u}$
