Question

Relate the image distance ( $v$ ), object distance ( $u$ ) , image height ( $h^{^{'}}$ ) and object height ( $h$ ) to the formula of magnification $(M)$ for a mirror.

$M = \frac{h}{h^{'}}$ = $\frac{v}{u}$

Solution

The correct option is C
$M = \frac{h^{'}}{h}$ = $\frac{- v}{u}$

$M = \frac{h^{'}}{h}$ = $\frac{- v}{u}$ where h' is the image height, h is the object height, v is the image distance and u is the object distance.
