The work function of the cathode of a photocell in a circuit is 6 10 19 J Ultraviolet wave of wavelength 250 nm hits the cathode perpendicularly If we change the frequency of the radiation at most by what factor can the linear momentum of the emitted electron be greater than that of the entering photon Take h 6 6 x 10 34 J sec m 9 10 3 kg
