X-RAY DIFFRACTION (DEBYE-SCHERRER METHOD)
people.sabanciuniv.eduThe experiment consists of analysing two x-ray films exposed in a powder diffraction camera. In the powder (Debye-Scherrer) method, the x-rays fall on a mass of tiny crystals in all orientations, and the diffracted beams of each order h, k, l form a cone. Arcs of the cones are intercepted by a film surrounding the specimen.

The second method is often used to determine the structure of an unknown crystal by performing an x-ray diffraction experiment. If electrons act like waves, we should be able to apply Bragg’s Law to the diffraction of electrons.
