Electrons ejected from the surface of a metal, when light of certain frequency is incident on it, are stopped fully by a retarding potential of 3 volts. Photo electric effect in this metallic surface begains at a frequency `6xx10^(14)s^(-1)`. The frequency of the incident light in `s^(-1)` is `[h=6 x10^(-34) J-sec`, charge on the electron =`1.6xx10^(-19)C`]
