X-ray scattering
Quick Summary
X-ray scattering is a technique used to study the structure of materials by observing how X-rays interact with them. When X-rays strike a crystal, their waves are diffracted by the regularly spaced atoms, creating an interference pattern. This pattern is described by the Bragg law, which relates the wavelength of the X-rays, the spacing between atomic planes in the crystal, and the angle of incidence.123
By analyzing these diffraction patterns, scientists can determine the arrangement of atoms within crystals, which is crucial for understanding material properties. X-ray scattering is also used to study liquids and amorphous solids, providing information about near-neighbour distances. This method has been instrumental in determining the structures of complex molecules like DNA and hemoglobin.41

…nature (could be polarized) by scattering from certain materials. These properties suggested that the rays were another form of electromagnetic radiation, a possibility that was postulated earlier by the British physicist J.J. Thomson. He noted that the electrons that hit the glass wall of the tube would undergo violent accelerations…

Arthur Holly Compton…could not explain why the scattering of a wave should increase its wavelength. Compton initially theorized that the size and shape of electrons in the target atoms could account for the change in the X-rays’ wavelength. In 1922, however, he concluded that Albert Einstein’s quantum theory, which argued that light…
