Question

The relation between focal length (f) and radius of curvature (R) of a spherical mirror is

• A. \( R = \frac{f}{2} \)
• B. \( f = \frac{R}{2} \)
• C. \( R = f \)
• D. \( R = \frac{f}{3} \)

Hint:

Remember the formula \( f = \frac{R}{2} \) when dealing with spherical mirrors.

Answer 1

The Correct Option is B

The relationship between the focal length \( f \) and the radius of curvature \( R \) for a spherical mirror is given by: \[ f = \frac{R}{2} \] This formula is valid for both concave and convex spherical mirrors.
