Chapter 15, Problem 15A.3AE

Interpretation Introduction

Interpretation:

The separations of the given planes in a crystal having a cubic unit cell have to be determined.

Concept Introduction:

Separation of a plane in a cubic unit cell:

  $\begin{array}{l}\frac{1}{d_{hkl}^2}=\frac{h^2+k^2+l^2}{a^2}\\ or\\ d_{hkl}=\frac{a}{\sqrt{h^2+k^2+l^2}}\end{array}$

Where,

$d_{hkl}=$ Separation between planes

a, b and c are unit cell parameters.

h, k and l are Miller indices.
