Question

What is breggs equation explain

Answer 1

The equation explains why the faces of crystals reflect X-ray beams at particular angles of incidence (Θ, λ). The variable d indicates the distance between the atomic layers and the variable Lambda specifies the wavelength of the incident X-ray beam.

Bragg's law, or Wulff–Bragg's condition, a special case of Laue diffraction, gives the angles for coherent and incoherent scattering from a crystal lattice. When X-rays are incident on an atom, they make the electronic cloud move, as does any electromagnetic wave.
