Question

Find the focal length of convex mirror whose curvature is 32 CM

Answer 1

As we know that the focal length of a spherical mirror is equal to half the radius of curvature of that mirror. According to the question the radius of curvature of a convex mirror is 32 cm. =16 cm. So, the focal length of the convex mirror is 16 cm

Answer 2

Answer:

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