Talk:K-alpha

The first line of the article suggests both emission and absortion K_alpha are a result of L <- K transitions, this is only the case for absorbtion, K alpha emission would be an L shell electron dropping to a vacant K orbital (such as when a metal sample is bombarded with electrons, a K electron is ejected and the atom relaxes and an x-ray is emmited, such a process occurs in an x-ray tube, for instance). This should be clarrified. 85.211.247.232 15:51, 7 June 2007 (UTC) r_edkins[reply]

Frequency confused with energy

The link to Mosley's law states that "the frequency of the line is adequately calculated..." but the equation given, and the associated example, calculates the energy, not the frequency. Geoffrey.landis (talk) 19:19, 4 March 2013 (UTC)[reply]

Technically you are correct and I've changed it to energy. But be advised that high energy physicists generally talk about frequency and energy as essentially the same thing, since they always differ only by the unit conversion factor h. So E = hf. Where E is in eV and f is in THz, then h is 1519.267365 THz/eV.S B H arris 02:36, 5 March 2013 (UTC)[reply]
