The fcc lattice can be considered as a simple cubic lattice with a basis or a bravais lattice in its own right. derive the reciprocal lattice vectors for each of those two situations. [10 marks] (d) calculate the length of the shortest reciprocal space vector normal to the (211) plane for an fcc lattice with unit cell equal to a. use this result to obtain the separation between each plane in the set of the (211) planes.
