What is the focal length of the water drop

Reference no: EM13659986

A drop of water on a countertop reflects light from a flower held 3.10cm directly above it. The flower's diameter is1.80cm and the diameter of the flower's image is 0.117cm. What is the focal length of the water drop, assuming that it might be treated as a convex spherical mirror?
