Moseley’s law for a series of homologous lines (1913) Moseley examined metals from aluminium to gold and he found that their X-ray spectra were similar but with a deviation that changed regularly through the series, according to Equations below. Theory X-ray radiation from a source consists of two main components: "braking radiation" and characteristic x-rays. The positions of the characteristic x-rays with respect to angle are governed by Bragg's law, which is a special case of Laue diffraction and gives the condition on the diffraction angle (θ) for complete constructive Module 1 comprises a series of x-ray laboratory exercises investigating basic principles, such as the verification of Moseley's law, Compton's law and the Lambert–Beer law. Bragg's law for X-ray diffraction . W.L. Bragg and W.H. Bragg studied the diffraction of X-rays in detail and used a crystal of rock salt to diffract X-rays and succeeded in measuring the wavelength of X-rays.. Consider homo-geneous X-rays of wave length λ incident on a crystal at a glancing angle θ. Henry G. J. Moseley 1887 - 1915 Brief biography Moseley was born in Weymouth, Dorset, England.

His father, Henry Nottidge Moseley was a professor of anatomy and physiology at Oxford, and his mother was the daughter of biologist John Gwyn Jeffreys. He studied mathematics and was introduced to the study of x-rays at Eton. In

Equation (2) can be derived by solving Schr€odinger’s equa-tion for an atomic system with an inﬁnitely heavy nucleus and one electron. In this video, we introduce Moseley’s law, which explains how periodicity is a property of an element’s atomic number rather than atomic mass. Also, we come Moseley’s Law: Moseley in 1919 studied the characteristic X rays of 38 elements using a crystal of potassium ferrocyanide as diffraction grating and a photographic screen developed by Bragg. Each ray of Barkla and Sadler was found to consist of two rays (e.g., K α and K β for K rays).

Moseley discovered a way to use x-rays in a vacuum to identify the atomic charge the reflected x-rays and the elements, which is now known as Moseley's law. 18 Sep 2008 Bragg reflection: diffraction of x-rays at a monocrystal. Moseley's law and determination of the Rydberg constant.

BACKGROUND: In 1913, Henry Moseley measured the frequencies of the X rays emitted by the elements and showed that X-ray frequencies could be used to deduce the atomic number Z of the element.

Moseley, working in Rutherford's Manchester laboratory, was engaged in cataloguing the characteristic x-ray spectra of series of elements. The definition
Moseley's law is an empirical law of the characteristic x-rays emitted by the atom.
It is historically important in quantitatively justifying the conception of the nuclear model of the atom, with all or nearly all positive charges of the atom located in the nucleus, and associated on an integer basis with atomic number.
