His groundbreaking work using X-rays revealed a fundamental relationship between the frequency of X...
In 1913, by using x-ray spectra obtained by diffraction in crystals, he found a systematic relation between wavelength and atomic number, Moseley's law. Previous to this, atomic numbers or elemental numbers had been thought of as a semi-arbitrary sequential ordering-number, based on sequence of...

The results of his study showed a clear and simple progression of the elements that was based on the number of protons in the atomic nucleus, rather than the order based on atomic weights that was then the basis of the Periodic Table. His work, called a "classical example of the ...
In 1913 he established the relation between the frequency of the spectral lines of characteristic X-radiation and the atomic number of the element (Moseley’s law.) He was killed in action during World War I. WORKS“The Reflection of the X-rays.” Philosophical Magazine, 1913, vol. 26, se...
