Question

Find the focal length of a convex mirror whose radius of curvature is 16cm

Answer 1

Answer:
Focal length = 1/2× Radius of curvature
= 1/2×16
=8 cm.
Thus, Focal length = 8 cm.

Good luck!

Answer 2

Answer:

$Focal \: length \: = \: \frac{Radius \: of \: curvature}{2} \\ or \: f = \frac{r}{2} \\ \\ f \: = \: \frac{16}{2} \\ \\ f = 8cm \\ \\ Thus, \: the \: focal \: length \: of \: convex \: mirror \: is \: 8cm.$
