The first four peaks in the X-ray powder diffraction pattern of sodalite are at 2 values of 9.97°, 14.12°, 17.32° and 20.02°. The radiation used for the experiment was Cu K with  = 1.5418 Å. Determine the lattice type and calculate the length, a, of the cubic unit-cell.

Assume that an X-ray diffraction pattern is taken from two specimens of pure Ni. The two specimens are identical except that one contains numerous twins, while the other is untwinned. Would the XRD patterns show a larger number of diffraction peaks for the specimen containing the twins? Explain the reasoning behind your answer.

what is the difference between x-ray imaging and the x-ray diffraction?

Using powder X-ray diffraction to analyse a metal compound, a simple pattern of peaks resulted, where the largest peak existed at an angle of 2θ= 19.8°. However, when a similar sample was analysed that contained a metallic impurity, this 2θ value became 22.4°. What does this suggest is happening to the crystal lattice and why?
