Question

find the focal length of a convex mirror whose radius of curvature is 32cm

​

Answer 1

$\huge{\mathfrak{\boxed{\blue{Solution}}}}$

Formula:

$\large{Radius\:of\:curvature=2(focal\:length}$

$\large{32cm=2(focal\:lengh)}$

$\large{32cm/2=focal\:length}$

$\large{\boxed{\orange{16cm=focal\:lengh}}}$

Answer 2

Explanation:

As it is convex mirror focal lenght f is positive.R=32.

R=2F=

F=R/2=32/2=16cm.
