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 540 nm, how many photons are emitted p second? (Assume three significant figures in this calculation.) Express your answer using three significant figures. radiation = 15. ΑΣΦ 1 ? photons per second
