Question

explain MOSELEY's Law

Answer 1

Moseley law is the empirical law concerning the characteristics x race that are emitted by atoms. the law was discovered and published by the English physicist Henry moseley in 1913.
in brief the law states that the square root of the least frequencies of emmited X-rays is proportional to the atomic number.

Answer 2

✴️Here's your answer:-
⚫Moseley’s Law

 is a law that relates the frequency of the spectral lines of the characteristic X-radiation of a chemical element to its atomic number. This law was experimentally established by H. Moseley in 1913. According to Moseley’s law, the square root of the frequency v of a spectral line of the characteristic radiation of an element is a linear function of its atomic number Z.

where R is the Rydberg constant, Sn is the screening constant, and n is the principal quantum number.

Mendeleev’s periodic system of the elements and the law helped to clarify the physical significance of Z.

According to Moseley’s law, the characteristic X-ray spectra do not display the periodic regularities that are inherent in optical spectra. This indicates that the inner electron shells of the atoms of all elements, which are manifested in the characteristic X-ray spectra, have an analogous structure.
