1 Photoelectric emission is observed from a metallic surface for frequencies v and v of the incident light v v If the maximum values of kinetic energy of the photoelectrons emitted in the two cases are in the ratio 1 n then the threshold frequency of the metallic surface is a C 1 1 n 1 nv v n 1 b d nv v n 1 1 1 n
