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?...
