Question

A parallel ray incident on the concave mirror is converged at 10cm from the mirror, then the radius of curvature of the concave mirror is ?​

Answer 1

Answer:

radius of curvature = 20

Explanation:

As parallel incident Ray passes through focus after reflection (in concave mirror)

=> given that ray converges at 10 cm i.e. focal length, f = 10 cm

and radius of curvature = 2f.
