9.12 Calculate the average power output of a photodetector that collects 8.0 x 10' photons in 3.8 ms from monochromatic light of wavelength (a) 470 nm, the wavelength produced by some commercially available light-emitting diodes (LED), and (b) 780 nm, a wavelength produced by lasers that are commonly used in compact disc (CD) players. Hint: The total energy emitted by a source or collected by a detector in a given interval is its power multiplied by the time interval of interest (1 J= 1 W s).
