Question

What is the focal length of a concave mirror with a radius of curvature of 16.0 cm?

Answer 1

Step 1:Given data

According to the question we have given:

The radius of curvature, $R=16cm$

We have to find the focal length of the concave mirror

Step 2: Calculating the focal length of the concave mirror:

The relation between focal length and radius of curvature of a concave mirror is given by

$f=\frac{R}{2}$

$=\frac{16}{2}$

$f=8cm$

Hence, the focal length of a concave mirror having radius of curvature 16 cm is 8 cm.
