Question

The wavelengths of the Kα lines for Ca and Zn are 3.36 and 1.44 Å. Use this information to calculate the approximate wavelength of the Kα line for V by linear interpolation

Answer 1

Here we assume that a linear relationship exists between the atomic number Z for the elements in question and the square root of the frequency v of their Κα lines This linear relationship can then be used to determine the frequencies and wavelengths of the other elements as shown in the spreadsheet.
