(C) According to Henry Moseley's law for characteristic $X$-rays,the frequency $v$ is related to the atomic number $Z$ by the equation: $\sqrt{v} = a(Z - b)$,where $a$ and $b$ are constants.This can be written as $v^{1/2} = a(Z - b)$.Comparing this with the given plot of $v^{n}$ versus $Z$,we get $n = 1/2 = 0.5$.
