Question

focal length of a convex mirror of
radius of curvature 48cm?

Answer 1

Radius of curvature=2×focal length.

so focal length=

radius of curvature/2

=48/2=24cm

hope it helps you frnd

Answer 2

Answer:

$Focal \: length \: = \: \frac{Radius \: of \: curvature}{2} \\ or \: f = \frac{r}{2} \\ \\ f \: = \: \frac{48}{2} \\ \\ f = 24cm \\ \\ Thus, \: the \: focal \: length \: of \: convex \: mirror \: is \: 24cm.$
