In an experiment of photoelectric effect, the graph of maximum kinetic energy `E_(K)` of the emitted photoelectrons versus the frequency v of the incident light is a straight line AB as shown in Figure below:
Find : (i) Threshold frequency of the metal.
(ii) work function of the metal
(iii) Stopping potential for the photoelectrons emitted by the light of frequency `v=30xx10^(14)` Hz.
