Bragg diffraction occurs when radiation of wavelength λ comparable to atomic spacings, is scattered in a specular fashion (mirror-like reflection) by the atoms of a crystalline system, and undergoes constructive interference. For a crystalline solid, the waves are scattered from lattice planes separated by the distance d between successive layers of atoms. When the scattered waves interfere const… http://www.rodenburg.org/theory/crystallography17.html

When they land on a piece of film or other detector, these beams make a diffraction pattern of spots; the strengths and angles of these beams are recorded as the crystal is gradually rotated. Each spot is called a r… chung\\u0027s braintree
