Prerequisites

Lab Activities

The students find the crystallographic orientation of a single crystal using the Laue method in which "white" x-ray radiation is diffracted from a single crystal. The crystals used are NaCl and KCl. In addition, they strain a NaCl crystal in a vice and observe the effect of plastic deformation on the Laue pattern.
