Problem
In an experiment on the photoelectric effect, light of wavelength 400nm is incident on a metal plate with power 5W. The collector plate is made sufficiently positive with respect to the emitter so that the current reaches its saturation value. Assuming that, on average, one out of every 106 photons ejects a photoelectron, find the photocurrent in the circuit.
