Crystal Plane 82 d sin 6. Crystal Plane ttl Ray reflected at 2nd plane has traveled 2d sin 9 further than ray reflected at first plane Incident X -ray Beam Diffracted X -ray Beam Figure 6. X-ray diffraction. The dotted lines show perpen- diculars to the wavefront. For re-enforcement, the rays reflected at planes 1 and 2 must travel distances which differ by a whole number of wavelengths. This will be fulfilled if nX = 2d sin 6 where n is an integer. in a fixed direction. However, because A will not be known, one cannot find the distance between reflecting planes from a Laue Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Ackerman, Eugene, 1920-.
