- Light of wavelength 340 nm, 600 nm and 680 nm is incident on a metal. Electrons are not emitted from the metal, which of the following is the most likely scenario. The energy of the photon for 600 nm light corresponds to the work function of the material. The energy of the photon for 680 nm light corresponds to the work function of the material. The work function is less than any of these photon energies. The work function is more than any of these photon energies. The energy of the photon for 340 nm light corresponds to the work function of the material.You use 0.124 nm x-ray photons in a Compton-scattering experiment.
