The correct relation between the radius of curvature R and focal length f for a spherical mirror is:

Correct option is A

The correct answer is (A)$$​​\frac{R}{2}=f$$​

• A spherical mirror is a mirror whose reflecting surface is a part of a hollow sphere of glass.
• One side of the mirror is well polished and reflecting, and another side of the mirror is opaque (often painted red).
• Spherical mirrors are of two types - convex mirror, and Concave mirror. The image formed by the spherical mirrors depends on the position of the object.

• => $$R = 2f$$​​
