Physics

In an XRD pattern using Cu Kα radiation, a certain cubic crystalshows peaks at 2θ values (in degrees) of 44.3, 64.4, 81.6, 98.0. Itis known that the size of the cubic crystal is greater than 2.5Angstroms. Based on this information and the location of the peaks,we conclude that the lattice of the crystal is

1. simple cubic                      2. face centered cubic

3.     body centered cubic       4.    none ofthe other choices
