THE experimental results reported in a previous communication 1 confirm the existence of several maxima for the second- and the third-order diffraction lines at oblique incidence and at low sound ...

IT has been well established by several investigators 1,2 that, in the case of diffraction of light by ultrasonic waves, the first orders of diffraction on either side of the central zero order appear ...
