A watt is a unit of energy per unit time, and one watt (W) is equal to one joule per second (J-s-1). A 40.0 W incandescent lightbulb produces about 5.00% of its energy as visible light. Assuming that the light has an average wavelength of 510.0 nm, calculate how many such photons are emitted per second by a 40.0 W incandescent lightbulb. number of photons per second:
