Chapter 12.6, Problem B12.1P

Interpretation Introduction

Interpretation:

The spacing between layers of $\text{Ni}$ atoms is to be calculated.

Concept introduction:

The Bragg equation gives the relation between the angle of incoming light and wavelength of light. The chemical equation of the Bragg equation is as follows:

$n\lambda =2d\mathrm{Sin}\theta$ (1)

Here,

$n$ is the order of the diffraction.

$\lambda$ is the wavelength of light.

$d$ is the distance between layers.

$\theta$ is the angle of the incoming light.
