Please write all details

2. Calculate the lattice parameter [a], the interplanar spacing.[d] and determine the expected diffraction angle (20) for the first-order reflection from the (111) set of planes for FCC lead (Pb) when monochromatic radiation of wavelength 0.1542 nm is used. The value of R (1.75 nm). "Note: A first-order reflection occurs when n = 1 and the scattered and incident waves have a path difference of one wavelength
