When photon of energy 4 0 eV strikes the surface of a metal

Last updated: 6/11/2023

When photon of energy 4 0 eV strikes the surface of a metal A the ejected photoelectrons have maximum kinetic energy TA eV end de Broglie wavelength AA The maximum kinetic energy of photoelectrons liberated from another metal B by photon of energy 4 50 eV is TB TA 1 5 eV If the de Broglie wavelength of these photoelectrons Ag 2 A then the work function of metal B is 1 3eV 2 2eV 3 4eV 4 1 5eV
