The same photosensitive metal is first illuminated by monochromatic radiation of wavelength λ and then by radiation of wavelength 2λ. Both wavelengths are shorter than the threshold wavelength, so photoelectric emission occurs in both experiments. If the corresponding maximum photoelectron kinetic energies are K₁ and K₂, and the work function of the metal is φ, which relation is correct?
