Fig. 38-20 Diffraction pattern formed by aperture w diam = D

Fig. 38-19 A cubic crystal and two different families of crystal planes. The spacing of the planes in (a) is d = a (2) -1/2 (b) is d = a (3) -1/2 There is another set of planes parallel to the cube faces with spacing a. Fig. 38-20 Diffraction pattern formed by aperture w diam = D.
