    can anyone tell me why we use reciprocal lattice for understanding the diffraction of X rays from crystal?????????????????
    thanks in advance :)

    X-ray diffraction takes place only when a reciprocal lattice point lies on Ewald's sphere of reflection.Hence photographic record of the diffracted x-ray beams is nothing but a photographic record of the reciprocal lattice.

    Once you learn the graphic representation of Bragg's law in terms of the reciprocal lattice vector you will appreciate the geometrical concept of reciprocal lattice.
