Bragg Equation or Bragg’s Law
describes the physical phenomenon of X-ray scattering from a crystallo- graphic three-dimensional lattice plane as nl=2dsinq, in which n is any integer, l is the wavelength of the X-ray, d is the crystal plane separation, also known as d-spacing, and q is the angle between the crystal plane and the diffracted beam, also known as the Bragg Angle.
