Question

if the focal length of spherical mirror is 12.5 cm less the radius of curvature will be ​

Answer 1

Answer:

Focal length, f = 12.5 cm

Explanation:

Then, the radius of the curvature of a spherical mirror = 2 times of focal length

Which is given as-

R=2xF

R=2x12,5cm(putting the value of F)

R=25cm
