X-ray diffraction spectrometer

An X-ray spectrometer is an instrument used to measure the angles of X-ray diffraction or to analyze X-ray spectra. X-ray diffraction occurs when X-rays scatter off the atoms in a crystal, creating an interference pattern that reveals information about the crystal's structure or identifies crystalline substances.12

This phenomenon is based on the Bragg law, which states that constructive interference occurs when the path difference between X-rays reflecting off atomic planes is a whole number of wavelengths (nλ = 2d sin θ). This principle allows scientists to deduce the internal structure of crystals by observing these diffraction patterns. X-ray spectroscopy, developed by physicists like the Braggs, uses these diffraction patterns to measure and identify X-ray wavelengths, forming the basis for understanding atomic structure and elemental composition.34
