The primitive lattice vectors for a given crystalline solid are a1-alj, and a2 = a2[{cos(phi)) H(sin(phi) i The magnitudes of these primitive vectors are al = 2 Angstrom nm, a2 = 4 Angstrom, and the angle between them is 60 degrees. The reciprocal lattice has primitive vectors with magnitudes b1 and b2, respectively, as a. 4.47, 8.94 b. 72.5, 36.25 c. 362.5, 725 d. 725, 362.5 e. 36.25, 72.5
