Question

Find the focal length of a convex mirror whose radius of curvature is $32cm$.

Answer 1

Step 1: Given data

The radius of curvature, $R=+32cm$

Step 2: Calculate Focal Length

The focal length of a spherical mirror $=$ half of the radius of curvature of the mirror.

$f=\frac{R}{2}$ where, $f$ is the focal length of the mirror.
$=\frac{32}{2}=16cm$

Hence, the focal length of the given convex mirror is $16cm$.
