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

 

Answer

Radius of curvature = 32 cm

 

We know that

Focal length is equal to half of Radius of curvature

 

Therefore,

Focal length = Radius of curvature / 2

                   = 32/2

                   = 16 cm

 

The focal length is 16 cm
