                                      Photoelectric Effect






                                       Interaction of photon has a particle-particle collision with an

                                            atomic electron







                                       Photon transfers all of its energy to the electron






                                       If the energy is sufficient to release the electron from its atomic

                                            orbit, the atom is ionized
