Investigated Crystal Structures

Max von Laue's discovery that diffraction patterns occur when X-rays pass through crystals inspired William and Lawrence Bragg to conduct their own studies in the area. Their contributions included establishing the relationship between the wavelength of the X-ray, its angle of incidence, and the distance between the atomic layers inside the crystal. This provided a powerful tool for studying crystals' structures. Using diffraction pattern methods, it now also became possible to calculate the positions of atoms in crystalline structures.
