diffraction instrument wherein the detector screen is positioned exactly 0.25 m away from a crystal sample (analyte) and the electrons from the source have an energy of 12.4 kev. Following an experiment we observe the diffraction pattern shown (below) left. A slice through the center of this pattern (dashed yellow line) yields the interference pattern shown on the right, wherein the first dark spot is located 3.15 cm from the centerline. Using this information calculate the lattice constant (interatomic spacing) of the crystal. 13.15 cm
