Question

The focal length of a convex mirror is equal to its radius of curvature.

• A. True
• B. False

Answer 1

The correct option is B False

1. Focal length (f) is half the radius of curvature (R).
2. Mathematically it is given as, $f=\frac{R}{2}$
3. Note: The radius of curvature is the distance from the pole to the centre of curvature (C) of a spherical mirror.

Hence, the given statement is false.
