WebNow you can present the equation for photoelectric emission: Energy of photon E = h × f Picture a photon transferring energy to one of the electrons which is least tightly bound in the metal. The energy of the photon does two things. Some of it is needed to overcome the work function Φ. When photon energies are as high as the electron rest energy of 511 keV, yet another process, the Compton scattering, may take place. Above twice this energy, at 1.022 MeV pair production is also more likely. Compton scattering and pair production are examples of two other competing mechanisms. Even if the photoelectric effect is the favoured reaction for a particular interaction of a single ph…

Low frequency light (red) is unable to cause ejection of electrons from the metal surface. At or above the threshold frequency (green) electrons are ejected. Even higher frequency incoming light (blue) causes ejection of the ... birthday games ideas
