"WebMoseley's Law describes the relationship between atomic number and frequency of a spectral line of characteristic X-rays. When the square root of the frequencies of the characteristic X-rays from the elements is plotted against the atomic number, a straight line is obtained following the equation: ν = a (Z − b).

http://snst-hu.lzu.edu.cn/zhangyi/ndata/Moseley%27s_Law.html WebHistory. Using x-ray diffraction techniques in the 1910s, Henry Moseley found that the most intense short-wavelength line in the x-ray spectrum of a particular element was related to the element's atomic number, Z.This line was known as the K-alpha line. Moseley found that this relationship could be expressed by a simple formula, later called Moseley's Law.
