Which statement below concerning the photoelectric effect is true? View Available Hint(s) Increasing the intensity (amplitude) of the light shining on a metal surface is sufficient to cause the emission of electrons from a metal surface. A threshold wavelength exists for each metal, and only light of a longer wavelength than this threshold causes electrons to be emitted from the metal surface. Joy A threshold frequency exists for each metal, and only light of a frequency higher than this threshold causes electrons to be emitted from the metal surface. Light with a frequency below the threshold frequency can still cause electrons to be emitted from the metal surface, but a lag time occurs while sufficient energy to dislodge the electrons builds up.
