Photons (photon) of the original call is light quantum (light quantum), the quantum of electromagnetic waves. Historical 20th century, the German physicist Max Planck proposed a hypothesis that electromagnetic waves (including light) can only be an energy package in the form of the quantum to be emitted or absorbed. He found that, based on this assumption, the phenomenon of blackbody radiation can be well explained. In 1905, Einstein showed that light quanta real existence, now called photons. Photon theory can well explain the photoelectric effect.
