1. The powder pattern of zinc is obtained with a Hull/Debye-Scherrer camera with a diameter of 5.73 cm by CuKa radiation. (1) Calculate the resolution required to separate the 11.0 and 10.3 intercept lines. (2) Calculate the resolution of the camera used on this line. Suppose the line width is 0.03 cm. (3) How much minimum camera radius is needed to separate this line?
