Chapter 11, Problem 127RQ

Interpretation Introduction

Interpretation:

The relative angle of an X-ray, with the wavelength of $229\text{ pm}$, diffracted from crystal planes at the given different distances of layers of atoms are to be determined.

Concept Information:

Bragg equation is the equation that gives the relation between the wavelength of X-rays, $\lambda$, and the distance between the layers of the atoms, $d$, in the crystal and the relative angle of reflection or diffraction, $\theta$, from the layer of the atoms, that is, $n\lambda =2d\sin \theta$.
