Question

Which one of the following is focal length of the convex mirror whose radius of curvature is 32cm ?

Answer 1

Hi Friend ✋✋✋

Radius of the curvature , R = 32 cm

Focal Length , f = R / 2

f = 32 / 2

f = 16 cm

Hope it helps :-)

Answer 2

Answer:

$Focal \: length \: = \: \frac{Radius \: of \: curvature}{2} \\ or \: f = \frac{r}{2} \\ \\ f \: = \: \frac{32}{2} \\ \\ f = 16cm \\ \\ Thus, \: the \: focal \: length \: of \: convex \: mirror \: is \: 16cm.$
