this is a three part question if you dont answer all three parts i will downvote and report you to chegg support. please answer all three parts thank you.

X-ray diffraction pattern of gold as shown below has the FCC crystal structure. A monochromatic X-ray with a wavelength of 0.1542 nm was used. The reflection order is 1 points).
