Question

Am object is placed at the centre of curvature of a concave mirror, the distance between its image and the pole is
​

Answer 1

Answer:

Given: u=−2f f=−f (concave mirror)

To find : v

Solution: From mirror formula

$\frac{v}{1} + \frac{1}{u \: } = \frac{1}{f \: } \: \: \\ \\ \frac{1}{v} - \frac{1}{ - 2f} \: = \frac{ - 1}{f} \\ \\ \frac{1}{v} - \frac{ - 1}{2f} \\ \\ v = - 2f$
