Question

write relation between focal length and radius of curvature​

Answer 1

Answer:

The relation between focal length (f) and radius of curvature (R) of a spherical mirror is that the focal length is equal to half of the radius of curvature i.e. f=R2

Answer 2

Answer:

Radius of curvature is twice the focal length

Explanation:

Let radius of curvature​ = R

Focal Length = f

Then R = 2f
