Question

the focal length of a convex mirror is 8 cm find its radius of curvature​

Answer 1

Explanation:

Radius of curvature = 2 focal length

or

radius of curvature = 2 × 8 = 16

hence radius of curvature = 16 cm

Answer 2

Given,

Focal length of the convex mirror=8cm

To Find,

Radius of curvature of the mirror.

Solution,

We know the value of focal length and from that we have to calculate radius of curvature of the mirror.

For this we have the formula that ,

Radius of the curvature=2×focal length of the mirror

So, Radius of the curvature=2×8cm

                                             =16cm

Hence, the radius of curvature is 16cm.
