X-ray Diffraction of Cu (FCC) using X-rays of wavelength =1.54Å gives XRD pattern where one of the peaks occurs at 2=43.2º What are the Miller indices for this peak? Given atomic radius for Cu is 0.128nm (note a=22 r)

The Miller indices for this peak is ( 111 ).

This problem can be solved by applying Bragg's law.

The detail calculation is shown below.
