Purpose: Show analog between diffraction of light by a two-dimensional grating and diffraction of x-rays by a single crystal.
Description: A laser beam is incident on a two-dimensional grating, resulting in a diffraction pattern which has the symmetry of the grating and is similar to the diffraction pattern of x-rays from a single crystal with that symmetry. A variety of optical crystals is available, as seen in the photographs above.
