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.
