The emitted electrons are called photoelectrons and the current so produced is called photoelectric current. Planck’s Quantum Theory – It states, “One photon of light carries exactly one quantum of energy.” Wave theory of radiation cannot explain the phenomena of the photoelectric effect and black body radiation. When an electron strikes a zinc sulphide screen, a spot of light known as scintillation is produced.
