Linear regression plot of lattice constant calculation for different wavelengths
Linear regression plot of lattice constant calculation for different wavelengths
Analyze the relationship between diffraction spot spacing and lattice structure. Determine lattice constants and symmetry of different materials, evaluate how wavelength affects diffraction patterns, and apply crystallographic principles to distinguish between materials.

Measured lattice constants of 0.2128e-3 nm +/- 0.0046e-3 nm (glasses) and 8.71e-4 nm +/- 9.70e-6 nm (mystery sample). Identified four-fold vs. two-fold symmetry between samples. Confirmed experimentally that wavelength shifts diffraction spot positions but does not alter the fundamental lattice structure.
