One watt (W) is equal to 1 J/s. Assume that 5.0% of the energy output of a 75 watt light bulb is visible light and that the average wavelength of the light is 550 nm, how many photons per second are emitted by the light bulb? If 5.0% of the energy of a 75 watt light bulb is visible light, then the rate of energy of all the photons emitted is J/s (3 s.f.). A 550 nm wavelength is the...
