NO spamming❎❌✖​

Answer 1

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.

Answer 2

1. Focal Length = Radius of Curvature/2

so ,

Focal Length = 32/2 = 16 cm
