Photoelectric emission is observed from a surface for frequencies \(\nu_{1}\) and \(\nu_{2}\) of the incident radiation \(\left(\nu_{1}>\nu_{2}\right)\). If the maximum kinetic energies of the photoelectrons in the two cases are in the ration \(1: \mathrm{k}\) then the threshold frequency \(\nu_{0}\) is given by :
