You have two lightbulbs of different power and color, as indicated in (Figure 1). One is a 150-WW red bulb, and the other is a 40-WW blue bulb. Which bulb emits more photons per second? Which bulb emits photons of higher energy? Calculate the number of photons emitted per second by each bulb. Take λred=640nm�red=640nm and λblue=430nm�blue=430nm. (Most of the electromagnetic radiation given off by incandescent lightbulbs is in the infrared portion of the spectrum. For the purposes of this problem, however, assume that all of the radiated power is at the wavelengths indicated.)
