How does x-ray crystallography work

WebFirst was that the X-rays diffracted, or spread, proving that X-rays were waves. Second, these rays diffracted in particular directions depending on the nature of the crystal. … WebApr 4, 2024 · Since X-rays are waves of electromagnetic radiation, the atoms in a crystalline material can scatter the X-rays via the electrons of the atoms. The X-rays striking the electrons therefore produce secondary (spherical) waves, which emanate from the electron. This process is called `elastic scattering' where electrons act as the scatterer.
