Continuous and characteristic x-ray spectra

After combining the right hand parts of Eqs. 2.2 and 2.3 and solving with respect to X, it is easy to obtain the equation relating the shortest possible wavelength Q sw in A) and the accelerating voltage (in V). 

The transitions from L and M shells to the K shell, i.e. L - K and M- K are designated as Ka and KP radiation, respectively. Here K corresponds to the shell with principal quantum number n=l,Lton = 2 and M to n = 3. The Ka component consists of two characteristic wavelengths designated as Kai and Ka2, which correspond to Ipm - 1 1/2 and 2/73/2 - lsi/2 transitions, respectively, where s and p refer to the corresponding orbitals. The subscripts 1/2 and 3/2 are equal to the total angular momentum quantum number, j. The Kp component also consists of several spectral lines, the
