In this worksheet, we will practice determining the stoichiometry of crystals from systematic absences and the relative diffracted beam intensities.
When X-rays of wavelength 0.1315 nm are diffracted by a crystal, the first-order reflection occurs at an angle . Calculate to 3 significant figures the spacing of the crystal planes that give rise to this reflection.
X-rays of wavelength 0.147 nm are diffracted by a crystal with a layer spacing of 3.94 Å. Calculate the diffraction angle of the first-order reflection.
