WebJan 2, 2024 · The atomic planes of a crystal cause an incident beam of x-rays (if wavelength is approximately the magnitude of the interatomic distance) to interfere with one another as they leave the crystal. The phenomenon is called x-ray diffraction. WebMar 10, 2024 · "Bragg diffraction" is our name for what a Bragg grating does to light. Interference is what happens when light waves having different phases are superimposed. Diffraction is a name for interference, usually in the cases where the phase difference is due to the waves moving in different directions.

WebBragg’s law is the foundation stone on which the edifice of x-ray diffraction stands.
