Calculate the amount of energy contained in a photon (a quantum of visible light), of wavelength 590 nm. Express the energy in Joules. Suppose that a lamp, a source of yellow light, is sending out radiation of this single wavelength (590 nm) at the rate of one watt. How many quanta of radiation (i. e. How many photons) are emitted each second?
