Chapter 21, Problem 21.23E

Interpretation Introduction

Interpretation:

The form of Bragg’s law in terms of the angle made with the perpendicular to the crystal plane is to be derived.

Concept introduction:

A unit cell of the crystal is the three-dimensional arrangement of the atoms present in the crystal. The unit cell is the smallest and simplest unit of the crystal which on repetition forms an entire crystal. The parameters of a crystal can be obtained experimentally by X-ray diffraction technique.
