Homework Help: chemistry

Posted by Maria on Saturday, January 22, 2011 at 11:42am.

Light bulbs emit a broad spectrum of light; that is, they emit photons with a broad range of wavelengths. Suppose that 10% of the photons from a 75-Watt (on watt is one joule per second) bulb are emitted with an average wavelength of 500 nm (middle of the green rage, where our eyes are most responsive). How many photons per second are emitted by the bulb?
