Chapter 15, Problem 15B.3AE

Interpretation Introduction

Interpretation:

The values of the angle $\theta$ of the three diffraction lines of an orthorhombic unit cell have to be calculated.

Concept Introduction:

Bragg’s law:

  $n\lambda =2d_{hkl}\sin \theta$

Where,

$\lambda =$ Wavelength of incident light

$d_{hkl}=$ Interplanar distance

For orthorhombic unit cell, $\frac{1}{d_{hkl}^2}=\frac{h^2}{a^2}+\frac{k^2}{b^2}+\frac{l^2}{c^2}$

$2\theta =$ Glancing angle
