XRD is a primarily used to study crystalline materials . It relies on the fact that X-ray wavelengths are similar to the distance between atoms in a crystal lattice—roughly 0.1 to 10 nanometers.
This constructive interference only occurs when the geometry of the beam satisfies Bragg’s Law ( X-Ray Diffraction Imaging: Technology and Appli...

). By measuring these specific angles, scientists can calculate the precise spacing between atomic planes. The Future: What’s Next
The resulting output is a pattern of peaks. Each peak's position, intensity, and width reveal detailed information about the material's phase, crystal quality, and internal stress. Modern Technology Trends (2026)
Because the atoms are arranged in regular, repeating planes, these scattered rays interfere with one another. If the waves align perfectly (at specific angles), they amplify each other—a phenomenon called constructive interference .
