Question

The radius of curvature of spherical mirror is 20cm what is the focal length

Answer 1

Answer:

10cm

Explanation:

Since,

Radius of Curvature=20cm

Focal Length=

$\frac{1}{2}$

Radius of Curvature

=

$\frac{1}{2}$

x 20

= 10cm

Therefore, the Focal Length of the Spherical Mirror is 10cm
