The dispersion of the diffractometer (dθ/dλ) can be expressed in the given form obtained by differentiating the Bragg law = 2dsinθ
$$ \frac{{d\theta }}{{d\lambda }} = \frac{n}{{2d}} \cdot \frac{1}{{\cos \theta }} $$
where the angular separation (dθ) of two wavelengths separated by (dλ) is expressed in terms of the diffraction angle θ for a certain spacing d. n is an integer which can be taken as equal to 1.
