The kinetic energy of electrons ejected by using light having frequency equal to threshold frequency (v_(0)) is:

The number of photoelectrons emitted per unit time depends on (v gt v_(0))

The work functions of metals A and B are in the ratio 1 : 2 . If light of frequencies f and 2 f are incident on the surfaces of A and B respectively , the ratio of the maximum kinetic energy of photoelectrons emitted is ( f is greater than threshold frequency of A , 2f is greater than threshold frequency of B )

Photoelectric emission is observed from a metallic surface for frequencies v_(1) and v_(2) of the incident light. If the maximum value of kinetic energies of the photoelectrons emitted in the two cases are in the ratio n:1 then the threshold frequency of the metallic surface is
