…can be read from the patterns that are formed when various portions of the diffracted electron beam cross each other and by interference make a regular arrangement of impact positions, some where many electrons reach and some where few or no electrons reach. Some advanced analytical techniques, such as LEEDX…

- In spectroscopy: X-ray spectroscopy
Because the details of the diffraction patterns depended on the wavelength of the radiation, these experiments formed the basis for the spectroscopy of X-rays. The first spectrographs for this radiation were devised in 1912–13 by two British physicists—father and son—William Henry and Lawrence Bragg, who showed that there existed not…

…the physical structure from the diffraction patterns. The atomic structures of deoxyribonucleic acid (DNA) and hemoglobin were determined through X-ray crystallography. X-ray scattering is also employed to determine near-neighbour distances of atoms in liquids and amorphous solids.
