Webphotoelectric effect, in which an X-ray photon removes an electron from an atom or molecule. The kinetic energy of that electron depends upon the photon energy and the energy required to remove the electron (the binding energy) according to the equation: In an XPS spectrometer, the kinetic energy of the emitted electron is measured. WebFor instance, violet light has a shorter wavelength than red light and thus violet light has higher energy. Likewise, a 60keV x-ray photon and a 30 keV x-ray photon have the same …
