Question ThreeTwo aluminium samples, A and B, are to be examined using Bragg reflection. For sample A the first-orderBragg reflection from (111) planes occurs at an angle of 25°00', while for sample B the first order Braggreflection from (111) planes was at 25°20'. Aluminium atoms are 1.8 x 10-10 m diameter and form anFCC structure. X-radiation of wavelength 1.52 x 10-10 m is used for the analysis of two samples ofaluminium.Answer the following questions:(i)Calculate the lattice parameter of an aluminium atom.(ii)Calculate the interplanar distances for the two samples.(ii)Which sample shows pure aluminium, and what is the reason for the difference?(iv)Mention four uses of pure aluminium.
