If light of wavelength 412.5 nm is incident on each of the metals given below, which one will show photoelectric emission and why? .

The threshold frequency for a certain metal is 3.3xx10^(14) Hz. If light of frequency 8.2xx10^(14) Hz is incident on the metal, predict the cut-off voltage for the photoelectric emission.

In an experiment on photoelectric effect light of wavelength 400 nm is incident on a metal plate at rate of 5W. The potential of the collector plate is made sufficiently positive with respect to emitter so that the current reaches the saturation value. Assuming that on the average one out of every 10^6 photons is able to eject a photoelectron, find the photocurrent in the circuit.
