It is observed that characteristic X-ray spectra of elements show regularity. When frequency to the power 'n' i.e. $v^{n}$ of X-rays emitted is plotted against atomic number $Z$ , the following graph is obtained.

The value of 'n' is

The statement of moseley's law is: “The square root of the frequency of the x-ray emitted by an atom is proportional to its atomic number”.

$\sqrt{v} \propto Z - b$ So $n = \frac{1}{2}$

Moseley is the scientist most directly responsible for realizing that the structure of the atom is key to understanding the elements themselves.
