WebThe wavelengths of the Ag Kα1, Mo Kα1, Cu Kα1, and the Cr Kα2 have been established as secondary standards with probable error of approximately one part per million. Sixty-one additional x-ray lines have been used as reference values in a comprehensive review and reevaluation of more than 2700 emission and absorption wavelengths. WebIn 1914 Moseley proposed a law showing how the X-ray frequency can be related to the proton (atomic) number Z of the target material. If f is the X-ray frequency, then: X ray frequency (f) = k (Z- b) 2. where k and b are constants, k having a value of 2.48x10 15. Plotting a graph of Z against √f will give a straight line as shown in the ...
