In an experiment on photoelectric emission of `gamma`-rays on platinum, the energy distribution of photoelectron exhibits peaks at a number of descrete energies : 270keV, 339keV and 354keV. The binding energy of K,L and M shell in platinum are known to be 77keV, 13keV and 3.5keV approx., what is the wavelength of `gamma`-rays with which the data are consistent.
