(b) For m = 1 the above equation gives θ = 14.4°. The crystal should be turned 45 14.4 30.6 φ − ° = ° clockwise. (c) For m = 3 the above equation gives = 48.1°. The crystal should be turned 48.1 45 3.1 ° = ° counterclockwise. (d) For m = 4 the above equation gives = 82.8°. The crystal should be turned 82.8 45 37.8 ° counterclockwise. Note that there are no intensity maxima for m > 4 as one can verify by noting that m λ /2 d is greater than 1 for m greater than 4. 73. We want the reflections to obey the Bragg condition 2
