Interpretation Introduction

(a)

Interpretation:

The goniometer setting in terms of 2θ needs to be calculated for the Lβ1 lines of Br at 8.126 A0 when the diffracting crustal is ethylenediamine d-tartrate.

Concept introduction:

Bragg’s diffraction condition will be used for the calculation of angle for goniometer setting. This condition is given as-

nλ=2dsinθ

Where,

n = integer

λ= wavelength

d = interplanar distance of crystal

λ= angle
