Chapter 12.6, Problem B12.2P

(a)

Interpretation Introduction

Interpretation:

The wavelength $\left(\text{pm}\right)$ of the x-rays 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.

(b)

Interpretation Introduction

Interpretation:

The angle at which second-order diffraction appears is to be calculated.

Concept introduction:
