Question

focal length of a convex mirror is 10 centimetre and object is kept 20 cm from the pole of mirror find the position of image ​

Answer 1

Answer:

Explanation:

CONVEX MIRROR

u = - 20 cm

f = 10 cm

$\frac{1}{v}$ + $\frac{1}{u}$ = $\frac{1}{f}$

$\frac{1}{v} = \frac{1}{f} - \frac{1}{u}$

$\frac{1}{v} = \frac{1}{10} + \frac{1}{20}$

$\frac{1}{v} = \frac{2+1}{20}$

$\frac{1}{v} = \frac{3}{20}$

$v = \frac{20}{3} cm$
