Answer
In x-ray crystallography, an x-ray beam is passed through a sample, which is rotated to allow diffraction from different crystalline planes. The resulting patterns, representing constructive interference from various planes, are then analyzed to determine the crystalline structure. By using Bragg's Law for a given wavelength of light incident on atoms arranged in layers, we can measure the angle that produces constructive interference and then compute the distance between the atomic layers.
