Bragg's Law Demonstration


In the autumn of 1912, when he was only 22 years old, William Lawrence Bragg realised that X-rays could be used to detect the arrangement of individual atoms inside solid crystals. With his father's help he created a new science of X-ray crystallography.

For his insight, Lawrence Bragg became the youngest ever Nobel Laureate in 1915. He went on to become the Cavendish Professor of Experimental Physics. In 1953, more than forty years after his discovery he saw X-ray crystallography used to reveal the structure of DNA.
