Question

An unknown sample is analyzed by X-ray diffraction. An iron X-ray tube is used ($K_\alpha$=1.54Å). The following data are obtained. Complete the table using Bragg's Law ($I/I_o$ is the intensity/intensity of strongest peak expressed as a percent). $\theta$ Intensity (cps) 2.9 12481 8.8 12541 9.8 9406 13.3 15677 18.2 9249 20.2 6270 26.6 3135 d(Å) $(I/I_o) \times 100$
