Chapter 4, Problem 34P

Interpretation Introduction

Interpretation: Electron energy required to obtain the diffraction pattern for a surface with crystal spacing of 4.0 A⁰ should be calculated.

Concept Introduction:

The relation between the wavelength, crystal spacing, and angle of diffraction is as follows:

  $\begin{array}{l}\lambda =a\sin \theta \\ \lambda \text{= wavelength}\\ a\text{ = crystal spacing}\\ \theta \text{ = angle of diffraction}\end{array}$
