EFECTUL FOTOELECTRIC ...da A. Einstein in 1904-1905, plecand de la ipoteza cuantificarii a lui Plank. El admite ca radiatia luminoasa incidenta nu transporta energie in mod continuu, ca efectul fotoelectric corespunde transferului de energie de la un foton la un electron ciocnire foton-electron cu anihilarea fotonului conform bilantului de energie EMBED Equation.3 2 unde EMBED Equation.3 - lucrul mecanic de extractie EMBED Equation.3 - energia cinetica a fotoelectronului EMBED Equation.3 - energia foton electron incident.Masurat experimental au pus in evidenta o concordanta destul de buna intre teoria cuantica a lui Einstein si legile descoperite experimental astfel ca efectul foto- electric este o noua dovada a cuantificarii energiei purtata de radiatia luminoasa.
