Electron emission from a metallic surface by the application of light is known as photo electric emission
In this method, the energy of light falling upon the metal surface is transferred to the free electrons within the metal to enable them to leave the surface. The greater the intensity of light beam falling on the metal surface, the greater is the photo electric emission.
