X-rays scattered from a crystal will show constructive interference provided their wavelength ( λ ) fits the equation
2d sin θ = n λ
where d is the spacing between atoms of the crystal, θ the angle through which the rays have scattered and n is any whole number
This is the cornerstone of the science of X-ray crystallography.
