text: This early failure can be attributed to the very short wavelengths of X-rays (10−8 to 10−11 cm), which correspond to photon energies from 200 to 100,000 eV. In 1912 another German physicist, Max von Laue, realized that the regular arrangement of atoms in crystals should provide a natural grating of the right spacing (about 10−8 cm) to produce an interference pattern on a photographic plate when X-rays pass through such a crystal.
