Answer:
The radius of curvature of a spherical mirror is 20 cm.
Explanation:
The focal length of a 'spherical mirror' is half of its 'radius of curvature
more deep explanation:
Radius of curvature, R= 20 cm Radius of curvature of a spherical mirror = 2 — Focal length (f) R= 2f f= R/2 = 20 / 2 = 10 Hence, the focal length of the given spherical mirror is 10 cm
