This physical law was first derived from experiments resulting in the structures of sodium chloride and zinc sulfide.  
This physical law was first derived from experiments resulting in the structures of sodium chloride and zinc sulfide.  This law was derived from Ewald's theory of atomic distance and greatly simplifies the von Laue description of wave interference.  It is governed by a simple equation that relates the diffraction of X-rays in crystals at certain angles of incidence, stating that n lambda equals two d times the sine of theta.  FTP, identify this law named after a father and son pair who won a Nobel Prize for their work in 1915.
