Interplanar spacing equation
WebThe above three equations will be satisfied at various points as the crystal rotates. This gives rise to a diffraction pattern (shown in figure \(\PageIndex{2}\) as multiple h values). … WebNormally the planes with low index numbers have wide interplanar spacing compared with those having high index numbers. Moreover, low index planes have a higher density of atoms per unit area than the high index plane. In fact, it is the low index planes which play an important role in determining the physical and chemical properties of solids. 15.
