Probing the Structure of Solids: X-Ray CrystallographyDiffraction: Occurs when electromagnetic radiation is scattered by an object containing regularly spaced lines (such as a diffraction grating) or points (such as the atoms in a crystal).

Interference: Occurs when two waves pass through the same region of space.
