Find the focal length of a convex mirror whose radius of curvature is
32 cm
Answer
The focal length of a spherical mirror is equal to half the radius of curvature of that mirror.
The radius of curvature, R= 32 cm
Radius of curvature = 2 — Focal length (f)
R= 2f=
f = R/2 = 32/2 = 16
Hence, the focal length of the given convex mirror is 16 cm.
