The frequency$\mathrm{\nu }$of the characteristic X-ray of an element is related to its atomic number$\mathrm{Z}$by$\sqrt{\mathrm{\nu }}=\mathrm{a}\left(\mathrm{Z}-\mathrm{b.}\right)$

$\sqrt{\mathrm{\nu }}=\mathrm{a}\mathrm{Z}-\mathrm{a}\mathrm{b}$

Comparing this with$\mathrm{y}=\mathrm{m}\mathrm{x}+\mathrm{c}$where$\mathrm{a}$and$\mathrm{b}$are constants, we deduce that the graph will be a straight line with positive slope and negative intercept.
