Braggs x ray spectrometer
WebJul 2, 2024 · In 1913 Bragg and his son Lawrence developed the Bragg spectrometer method based on X-ray diffraction, which was initially used to determine X-ray spectra, … When an electron from the inner shell of an atom is excited by the energy of a photon, it moves to a higher energy level. When it returns to the low energy level, the energy which it previously gained by the excitation is emitted as a photon which has a wavelength that is characteristic for the element (there could be several characteristic wavelengths per element). Analysis of the X-ray emission spectrum produces qualitative results about the elemental composition of the specime…
