Question

if the focal length of a concave mirror is 25 cm what is it's radius of curvature​

Answer 1

Answer:

50 cm

Explanation:

Radius of curvature = 2 F

                                = 2 * 25

                                = 50cm

Answer 2

Explanation:

Given :-

Focal length of convex mirror,F = 25 cm

To find = radius of curvature

We know that,

$F = \frac{R}{2}$

$25 = \frac{R}{2}$

$25 \times 2 = R$

$R = 50 \: cm$
