![]() ![]() ![]() ![]() Determine the normal distance between the two planes.ģ.17 Draw the NaCl crystal structure. What is the length of the translation vector with $h = 4$, $k = 3$, and $l = 1$ ?ģ.16 Draw the (111) and (222) planes in a simple cubic unit cell, with lattice constant $a$. From this information determine the primitive lattice vectors. ![]() One way is to repeat the primitive unit cell at each translation vector, In a crystal, atoms are arranged in straight rows in a three-dimensional periodic pattern.Ī small part of the crystal that can be repeated to form the entire crystal is called a unit cell.Ī crystal can be specified in several ways.
