Bragg’s Law: The Relationship Between the Diffraction Pattern and the Crystal

Braggs Law

Bragg’s law allows you to determine the interplanar distance (d-spacing) in a crystal from the angles at which constructive interference occurs in a diffraction pattern.

nλ = 2dsinθ

n =integer multiple of wavelength

λ =wavelength

d =distance between (hkl) planes

θ =angle of constructive interference
