Abstract
RECENTLY one of us1 pointed out that the optical diffraction effects by supersonic waves in solids are to be interpreted on the basis of the Raman-Nath2 theory, taking due cognisance of the photo-elastic effects arising from the strains caused by the sound waves. A refined further development of this idea enables us now to offer an explanation for a curious effect observed by Hiedemann and Hoesch3. Their experiments with glasses show two diffraction patterns of different spacings. With crossed Nicols normal and parallel to the sound-wave, only the pattern with the larger spacing is observed. It consists of the first orders only, with the central one missing. With the crossed Nicols at ± 45° to the sound-wave, only the pattern with the smaller spacing appears, showing many orders, including the central one.
