Among the photoelectrons, emitted due to incidence of light of frequency f on a metal surface , only the electrons having the highest kinetic energy can ionise a hydrogen atom. If this experment is performed with light of frequency 5/6f , the photoelectron having the highest kinetic energy can excite a hydrogen atom and from this excited hydrogen atom a photon of wavelength 1215 Å is emitted . Determine the (ii) value of f. Given h=6.625 xx10^(-34)*s,c=3xx10^(8)*s^(-1), 1 eV=1.6 xx10^(-19)J , ionisation energy of hydrogen =13.62 eV.
