The figure below shows an x-ray diffraction pattern for -iron taken using a diffractometer and monochromatic x-radiation having a wavelength of 0.1542nm; each diffraction peak on the pattern has been indexed. Compute the interplanar spacing for each set of planes indexed; also determine the lattice parameter of Fe for each of the peaks. Look carefully at Figure 3.24. Try to read each value to the nearest tenth. If you are having difficulty with this problem, you may wish to review: Graphing Conceptual Overview What is 2 for each of the planes?
