Question : 38 of 180

Marks: +1, -0

The graph of kinetic energy of photoelectron versus frequency of incident radiation is shown for two metals M and N. We may definitely conclude

work function of M> work function of N
work function of M < work function of N
work function of M= work function of N
at the threshold frequency of M the kinetic energy of the photoelectron emitted by M is more than that emitted by N
