Chapter 9, Problem 73QRT

Interpretation Introduction

Interpretation:

The spacing between the planes of copper atoms under the given condition has to be calculated.

Concept Introduction:

Bragg’s law:

It relates the angle of a diffracted beam to the spacing of a given set of lattice planes.  Mathematically it can be represented as follows,

  $n\lambda =2d\sin \theta$

Where,

$\lambda =$ Wavelength of incident radiation

$d=$ Lattice spacing

$2\theta =$ Glancing angle

$n=$ Order of diffraction
