Potassium Iodide (chemical formula: KI) has a face-centered cubic structure (just like sodium chloride). If the distance between crystal planes is d = 0.353 nm and X-rays of wavelength l = 0.093 4 nm are used, what is the smallest angle q at which a diffraction maximum may be obtained?
 a. 9.92
  b. 7.60
  c. 13.3
  d. 15.5
  e. 6.52

Question 2

If the interplanar spacing of NaCl is 2.814  10-10 m, what is the predicted angle at which X-rays of wavelength 0.140 nm will be diffracted in a first-order maximum?
 a. 31.3
  b. 7.20
  c. 20.5
  d. 14.4
  e. 29.8
