The intensity and polarization of the light diffracted by supersonic waves in solids are calculated by considering the photoelastic effect due to the strains created by the elastic waves. For natural incident light the diffracted light is partially polarized. In glasses and cubic crystals the diffracted light is partially depolarized if the incident light is polarized. The intensities are evaluated with the help of the theory of Raman and Nath and it is shown that this theory explains the measurements better than Brillouin's approximation. The calculated intensity distributions for natural and polarized incident light agree with the observations of Schaefer and Bergmann on glasses, quartz and calcite. This agreement justifies Fues' and Ludloff's assumption that all forced vibrations of the same frequency oscillate with the same amplitude.
