Henry Moseley studied characteristic X -ray spectra of elements. The graph which represents his observation correctly is Given v = Frequency of X-ray emitted Z = Atomic number

Question

TestHub · Accepted Answer

Moseley's observation on characteristic $X$ -ray spectra of elements relates frequency $(v)$ of $X$ -rays emitted to the atomic number by the following relation:
$\sqrt{v} = a (Z - b)$
The plot of $\sqrt{v}$ vs $Z$ is linear.

Based on this observation, the periodic law defined as the physical and chemical properties of the elements are periodic functions of their atomic numbers.
