Question
How many lattice points are there in one unit cell of each of the following lattice?
(i) face centered cubic
(ii) face centered tetragonal
(iii) body centered.
Solution
Solution:
(i) One unit cell of a face-centered cubic has 8 lattice points are corners and 6 lattice points at faces, total 14 lattice points.
(ii) One unit cell of face-centered tetragonal has 8 lattice points are corners and 6 lattice points at faces, total 14 lattice points.
(iii) One unit cell of body centered has 8 lattice points are corners and 1 lattice points at faces, total 9 lattice points.
