What was discovered

Laue demonstrates that crystals diffract X-rays, proving at once that they are waves and that crystals are periodic lattices of atoms; the Braggs formulate the law that allows the structure to be deduced. X-ray crystallography is born.

Lawrence Bragg received the 1915 Nobel Prize at the age of 25, the youngest ever in Physics. Merged with 'X-ray diffraction and Bragg's law (structural crystallography)' (duplicate, 23-09-2026).
