A drop of water on a countertop reflects light from a flower held 3.5 cm directly above it. The flower's diameter is 2.2 cm, and the diameter of the flower's image is 0.12 cm. What is the focal length of the water drop, assuming that it may be treated as a convex spherical mirror, in centimeters?
**The answer is NOT .18cm!

15. A camera lens focuses light from a flower 8 cm in diameter and 30 cm from the lens or to a focal plane 6 cm behind the lens. There, a charge-coupled device (CCD) builds up charge in individual squares (pixels) of the CCD in proportion to the light received. The camera elec- tronics read the charges to form an image. a) What is the focal length of the lens? b) Is the image on the CCD erect or inverted?...
