The metal iridium has an FCC crystal structure. If the angle of diffraction for the (220) set

Question:

The metal iridium has an FCC crystal structure. If the angle of diffraction for the (220) set of planes occurs at 69.22( (first-order reflection) when monochromatic x-radiation having a wavelength of 0.1542 nm is used, compute

(a) The interplanar spacing for this set of planes, and

(b) The atomic radius for an iridium atom.
