Draw a tetragonal unit cell and mark on it a set of points that would define
(a) A face-centred lattice
(b) A body-centred lattice.
Demonstrate, by considering two adjacent unit cells, that a tetragonal face-centred lattice of dimensions a and c can always be redrawn as a body-centred tetragonal lattice with dimensions a/√2 and c.
