The photoelectric effect describes an event in which an electron absorbs a
photon resulting in the electron being ejected away from the atom originally
containing the electron. The electron is ejected with the following energy: h=Planck's constant=6.626068x10-34m2 kg/s f=frequency of the light B.E.=binding energy of the electron When the electron is ejected, X-rays may be emitted, if the electron was in a low energy level and another electron drops down an energy level to replace it. The Photoelectric Effect can only occur to an electron orbiting a nucleus. Otherwise, conservation of momentum could not be conserved. When the electron is ejected, the nucleus recoils in the opposite direction. |
