Bragg reflections

Bragg reflections occur when X-rays are scattered from the regularly spaced layers of atoms in a crystal. When X-rays hit the crystal at certain angles, they reflect off these layers in a way that causes them to interfere constructively, enhancing certain reflected signals. This pattern of reflections allows scientists to determine the crystal's structure and the arrangement of atoms within it. This technique, known as X-ray diffraction, is essential in fields like chemistry and materials science, helping researchers understand the properties of materials at the atomic level.
