The 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.
