An 80 W light source (eg a bulb) consumes predictably 80 W of electrical power. Assume that all of this energy (but about 5% is in the visible region) is converted to Light with a wavelength of 580 nm. a) Find the frequency of the emitted light. b) Calculate how many photons per second are emitted in the visible region. c) Is there a relationship between the frequency of the light and the number of photons emitted per second? Comment.
