Consider a crystal with simple cubic structure. When monochromatic x-ray radiation having a wavelength of 0.1 nm is focused on a powdered sample of the crystal, the angle of diffraction (20) for the (221) set of planes in this metal occurs at 60 degrees (for the first order reflection n=1). (a) Calculate the interplanar spacing for this set of planes. (4) (b) Calculate the lattice constant for this crystal. (3) (c) Sketch the diffraction pattern of the sample, and calculate the first three smallest angles of diffraction. (3)
