Physics · Dual Nature of Matter and Radiation
When a photon of energy 4.0 eV strikes the surface of a metal A, the ejected photoelectrons have a maximum kinetic energy TA (in eV) and a de-Broglie wavelength λA. The maximum kinetic energy of photoelectrons liberated from another metal B by a photon of energy 4.50 eV is TB = (TA - 1.5) eV. If the de-Broglie wavelength of these photoelectrons is λB = 2λA, then the work function of metal B is:
