2. (a) List the point coordinates for all atoms that are associated with the FCC and BCC unit cells. 123 ( 1 marks each) (b) If the point x,y,z lies on (hkl) plane, the value of (xh+yk+zl) equals to 1. In other words, the point x,y,z is NOT on (hkl) plane if (xh+yk+zl) is not 1 . (This is a erystallographic rule called "Weiss Zone Law".) This being said, tell if the statement below is true. 16 ( 2 marks each) b-1. The point 11 is on ( 1111 ) plane (True or False)? b-2. The point 14 is on the family of {201} planes (True or False)? b-3. The point 23 is on the family of {111} planes (True or False)
