Bragg diffraction (also referred to as the Bragg formulation of X-ray diffraction) was first proposed by Lawrence Bragg and his father, William Henry Bragg, in 1913 in response to their discovery that crystalline solids produced surprising patterns of reflected X-rays (in contrast to that of, say, a liquid). They found … See more In physics and chemistry , Bragg's law, Wulff–Bragg's condition or Laue–Bragg interference, a special case of Laue diffraction, gives the angles for coherent scattering of waves from a crystal lattice.

For protons, α-rays, and other ion rays, the peak occurs immediately before the particles come to rest. It is named after William Henry Bragg, who discovered it in 1903.

WebAs the reflection occurs only in a short wavelength range, the volume Bragg grating can also be used for injecting pump light into a laser resonator: even if pump and laser wavelength are very close together, the grating may reflect laser light and transmit pump light, or vice versa. WebWith hexagonal and rhombohedral lattice systems, it is possible to use the Bravais-Miller system, which uses four indices (h k i ℓ) that obey the constraint . h + k + i = 0..
