Unformatted text preview: The kinetic energy of the electron increased as u symbol increases As current increases light intensity increases If you increase the intensity of light then you should be able to extract electrons from any metal Einstein explains that light is made of photon and 1 photon is able to extract 1 electron Kinetic energy of the electron o Photochemical reactions o Atomic spectra Emission/ absorption of light by atoms depends on their electronic structure Na has a low electric state and when we had voltage to it we excite it and it goes to a higher E state....
