Bragg's law
Videos
In many areas of science, Bragg's law – also known as Wulff–Bragg's condition or Laue–Bragg interference – is a special case of Laue diffraction that gives the angles for coherent scattering of waves
Typical selected area electron diffraction pattern. Each spot corresponds to a different diffracted direction.

X-ray crystallography is the experimental science of determining the atomic and molecular structure of a crystal, in which the structure causes a beam of incident X-rays to diffract in specific direct

…laser source or perform global hyperspectral imagery (see Photon etc.). The measurement of the angles can be used to determine crystal structure, see x-ray crystallography for more details. As a simple example, Bragg's law, as stated above, can be used to obtain the lattice spacing of a particular cubic system through the…

Although diamonds (top left) and graphite (top right) are identical in chemical composition—being both pure carbon—X-ray crystallography revealed the arrangement of their atoms (bottom). In diamond, the carbon atoms are arranged tetrahedrally and held together by single covalent bonds. By contrast, graphite is composed of stacked sheets. Within the sheet, the bonding is covalent and has hexagonal symmetry, but there are no covalent bonds between the sheets.
