Bragg’s law:
In physics, Bragg’s law gives the angles for a coherent scattering of waves from a crystal lattice.
“Bragg’s law gives the angles for coherent scattering of waves from a crystal lattice. This law was originally formulated for X-rays upon crystals but is moreover relevant for all kind of quantum beams.”
Applications:
For the measuring of the Wavelength.
Determining Lattice spacing of Crystals.
Measuring the Scattering angle of Beam.
