Bragg's Law refers to the simple equation:
n
= 2d sin
derived by the English physicists Sir W.H. Bragg and his son Sir W.L. Bragg in 1913 to explain why the cleavage faces of crystals appear to reflect X-ray beams at certain angles of incidence (theta,). The variable d is the distance
between atomic layers in a crystal, and the variable lambda
is the wavelength of the incident X-ray beam (see applet); n is an integer. For more click here.
