A source of yellow light has a higher power than a source of blue light. (a) Is the number of photons emitted per second by the yellow source greater than, less than, or equal to the number of photons emitted per second by the blue source? (b) Choose the best explanation from among the following: A. The yellow source emits more photons per second, because ( 1) it emits more energy per second than the blue source and (2) its photons have less energy than those from the blue source. B. The yellow source has the higher power, which means its photons have higher energy than the photons from the blue source. Therefore, the yellow source emits fewer photons per second. C. The two sources emit the same number of photons per second because the higher power of the yellow source compensates for the higher energy of the blue photons.
