Choose your answer: Is "This kinetic energy (for each photoelectron) is independent of the intensity of the light, but depends linearly on the frequency; and if the frequency is too low (corresponding to a photon energy that is less than the work function of the material), no photoelectrons are emitted at all, unless a plurality of photons, whose energetic sum is greater than the energy of the photoelectrons, acts virtually simultaneously (multiphoton effect)" a good answer to the question "When the photon energy is less than the work function of the material the light is shone upon, how many photoelectrons are emitted?"
Options are: -yes; -no;
yes
