A diffraction pattern was obtained from an unoriented sample of polyethylene using CuK radiation. It consisted of three rings of radius 22.2 mm, 36.6 mm, and 19.7 mm. The specimen-to-film distance was 50 nm. If polyethylene is orthorhombic with lattice dimensions of a = 7.41 , b = 4.96 , and c = 2.54 , what planes give rise to observed scattering pattern.
