Question

Find the focal length of concave
mirror whose radius of curvature is 32cm

Answer 1

$\mathfrak{\huge{\red{\underline{\underline{Answer:-}}}}}$

As we know that the focal length of a spherical mirror is equal to half the radius of curvature of that mirror.

So, according to your question the radius of curvature of a convex mirror is 32cm.

And hence, the focal length would be>

■32÷2

■16 cm.

So the focal length of the convex mirror is 16cm.
