from Chapter 2,E ¼ hn ¼ hc=lTherefore, for the X-ray photon released when an L electron in a specific sublevel dropsdown to fill a vacancy in the K shell,hn ¼ hc=l ¼ FL FKHence the frequency of the emitted X-ray isn ¼ FL FKh (8:2)The frequency or wavelength for transitions between other sublevels and shells is calculatedin the same manner. Transitions are not possible between all available energy levels.
