William Henry Bragg

William Henry Bragg was a British physicist and chemist known for his pioneering work in X-ray crystallography, a technique that reveals the atomic structure of crystals. Along with his son, William Lawrence Bragg, he developed Bragg's Law, which relates the angle at which X-rays are scattered by a crystal to the spacing of its atomic layers. This groundbreaking work earned them the Nobel Prize in Physics in 1915. Bragg's contributions significantly advanced fields such as chemistry, material science, and medicine by allowing scientists to “see” the arrangement of atoms within solid materials.
