A 100-watt lightbulb radiates energy at a rate of 100 J/s. (The watt, a unit of power, or energy over time, is defined as 1 J/s.) If all of the light emitted has a wavelength of 515nm, how many photons are emitted per second? (Assume three significant figures in this calculation.) Express your answer using three significant figures.
