PROBLEM 8: An unknown cubic crystalline substance has been subjected to an X-ray diffraction experiment, using radiation of wavelength 1.54 . The following data has been obtained. Diffraction Peak Diffraction Angle, 2 #1 43.8 #2 50.8 #3 74.4 #4 90.4 Assuming that i) the order of reflection (n) is 1 for all diffraction peaks, independent of the h,k,l indices of the planes. ii) the lattice parameter is 3.5801 determine a) The h,k,l indices for each diffraction peak. b) Whether the crystal structure of this material is fcc or bcc....
