In photoelectric effect, photocurrent

When stopping potential is applied in an experiment of photoelectric effect, no photocurrent is observed. This means that

In an experiment on photoelectic effect, the graph between maximum kinetic energy (K_(max)) and frequency of emitted photoelectron from metal surface is found to be a straight line as shown in fig. Calculate (a) thereshold frequency. (b) work function of metal in electron volt. (c) Planck's constant and maximum kinetic energy of the emitted electron by light of frequency v=8xx10^(14)s^-1 .

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.
