Experiment: Bragg Reflection

Product Overview

Objective: Determine the lattice constants for crystals with a structure similar to salt (NaCl) Measurement of Bragg reflection is a key method for investigating monocrystals using X rays. It involves X rays being reflected by the various lattice planes whereby the secondary waves reflected by individual layers undergo constructive interference when the Bragg condition is fulfilled. If the wavelength of the X rays is known it is possible to calculate the separation between lattice planes. In this experiment various crystals which share the structure of salt (NaCl) are investigated and compared.
