Question

The radius of curvature of a concave mirror is -46cm what is its focal length

Answer 1

the relation between radius of curvature of a mirror and its focal length is give by:

f = R/2

therefore,

f = -46/2

f = - 23 cm...

Answer 2

Answer: -23 cm

Explanation:

Since Focal Length = 1/2 of radius of curvature

= -46/2 cm

= -23cm
