(a) Interpretation: The goniometer setting to observe the ka 1 lines for Fe (1.76 A 0 ), Se (0.992 A 0 ) and Ag (0.497 A 0 ) needs to be determined if the diffracting crystal is a topaz. Concept introduction: Bragg’s diffraction condition will be used for the calculation of goniometer setting. This formula is given as- n λ = 2 d sin θ Where, n = integer λ= wavelength d = interplanar distance of crystal θ= angle

Interpretation Introduction

(a)Interpretation:The goniometer setting to observe the ka1 lines for Fe (1.76 A0 ), Se (0.992 A0 ) and Ag (0.497 A0 ) needs to be determined if the diffracting crystal is a topaz.Concept introduction:Bragg’s diffraction condition will be used for the calculation of goniometer setting. This formula is given as-nλ=2dsinθWhere,n = integerλ= wavelengthd = interplanar distance of crystalθ= angle
