In 1887, Heinrich Hertz investigated the phenomenon of light striking a metal surface, causing the ejection of electrons from the metal. The classical theory of electromagnetism predicted that the PORA that the energy of the electrons ejected should have be have been proportional to the intensity of the light. However, Hertz observed that the energy of the dont of the interio electrons was independent the intensity of the from light. Furthermore, for low enough frequencies, no electrons were ejected, no matter how great the intensity of the light became.
