The relation between the focal length (f) and radius of curvature (R) of a spherical mirror is expressed as follows:

The focal length of the concave mirror is thus calculated using the given radius of curvature that is 150 cm.

Therefore, the focal length (f) = 150 cm / 2 = 75 cm

So, the focal length of the concave mirror is 75 centimeters.
