Chapter 12, Problem 113AE

Interpretation Introduction

Interpretation:

Using the Bragg equation, the distance between the planes of atoms responsible for diffraction in the given crystal is to be calculated.

Concept introduction: William and Lawrence Bragg determined that the relationship among the wavelength of the radiation ( $\lambda$ ), the angle at which the radiation is diffracted ( $\theta$ ) and the distance between planes of atoms in the crystal that cause the diffraction ( $d$ ) is given by the equation given below.

$n\lambda =2d\sin \theta$

To determine: The distance between the planes of atoms responsible for diffraction in the given crystal.
