Single crystal diffraction

X-ray diffraction is performed on a single crystal. The wave vector of the incoming x-ray beam is k and the wave vector of the diffracted beam is k' . Diffraction peaks are observed for the following scattering vectors q = k' - k.

(a) What are the primitive lattice vectors of the reciprocal lattice?

(b) What is the Bravais lattice (in real space) of this crystal?

(c) How could you determine the volume of the primitive unit cell in real space?
