The paper explaining this phenomenon begins with a section critical of the theory of blackbody   radiation, showing that an integral of energy with respect to volume equals infinity. That problem is  solved by assuming that energy "is discontinuously distributed in space." Some of the measurements   of this effect, which used to be associated with ultraviolet light, were made by Philipp Lenard, who  discovered that light intensity did not impact the amount of voltage required to stop rays produced  by light striking metal. Name this effect explained when the Planck hypothesis was applied by Albert  Einstein, leading to Einstein's Nobel Prize.
