Chapter 15, Problem 15B.1P

Interpretation Introduction

Interpretation:

The wavelength of the X-rays under the given condition has to be determined.

Concept Introduction:

Bragg’s law:

  $n\lambda =2d_{hkl}\sin \theta$

Where,

$\lambda =$ Wavelength of incident light

$d_{hkl}=$ Interplanar distance

$2\theta =$ Glancing angle

$n=$ Order of diffraction

  Density $=\frac{Z\times m}{V\times N_A}$

Where,

$Z=$ Formula unit

$V=$ volume of one unit cell

$N_A=$ Avogadro’s no.

$m=$ Mass of a substance per mole
