In a Photo electric effect experiment, A metal ‘X’ is irradiated by two incident radiations in two different experiments. If the ratio of incident frequencies is 1:2 and the ratio of kinetic energy of photo electrons is 1:3. Then the correct relation is (where ν1, ν2 are incident frequencies in experiment one and two respectively and ν0 is the threshold frequency of the metal ‘X’)
