Calculate the magnitude of the focal length and power of a spherical mirror that has a radius of 5.00 cm.

2.5 cm

40 D

Explanation:

When the radius of curvature of a lens is divided by 2 we get the focal length of the lens.

Focal length is given by

The focal length of the lens is 2.5 cm

When we divide 1 by the focal length in the unit of meters we get the power of a lens

Power of a lens is given by

The power of the lens is 40 D
