12 In Fig. 33-35, light travels frommaterial a, through three layers ofother materials with surfaces parallelto one another, and then back into an-other layer of material a. The refrac-tions (but not the associated reflec-tions) at the surfaces are shown. Rankthe materials according to index of re-fraction, greatest first. (Hint: The par-allel arrangement of the surfaces al-lows comparison.)Figure 33-35 Question 12.

As a single crystal is rotated in an x-ray spectrometer (Fig. 3.22a), many parallel planes of atoms besides AA and BB produce strong diffracted beams. Two such planes are shown in Figure P3.38. (a) Determine geometrically the interplanar spacings d1 and d2 in terms of d0. (b) Find the angles (with respect to the surface plane AA) of the n = 1, 2, and 3 intensity maxima from planes with spacing d1. Let = 0.626 and d0 = 4.00 . Note that a given crystal structure (for example, cubic) has interplanar spacings with characteristic ratios, which produce characteristic diffraction patterns. In this way, measurement of the angular position of diffracted x-rays may be used to infer the crystal structure. Figure P3.38 Atomic planes in a cubic lattice.
