Chapter 15, Problem 15B.2AE

Interpretation Introduction

Interpretation:

The values of the angle $\theta$ of the three diffraction lines of a cubic I 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 $=\frac{a}{\sqrt{h^2+k^2+l^2}}$

$2\theta =$ Glancing angle
