For a spherical mirror, the relation between focal length and radius of curvature is given by ____

Open in App

Solution

Since focal length of a mirror is given by $f = \frac{Radius of curvature}{2}$ hence distance between focus and mirror is equal to distance between focus and centre of curvature.
Answer: $R = 2 f$
