When photons of energy 5 eV strike the surface of a metal A the ejected photoelectrons have maximum kinetic energy K eV and de Broglie wavelength The maximum kinetic energy of photoelectrons liberated from another metal B by photons of energy 5 30 eV is K K 1 5 eV If the de Broglie wavelength of these photoelectrons is g 22 then find K3 in eV I
