Reflection of acoustic waves from a free surface has been calculated for a general nonfactorable plane of hexagonal Al(IO 3) 3. 2HIO 3.6H 2O. Results are expressed in terms of reflection fractions which give the fraction of the incident power/area that is reradiated in each of the reflected waves. Calculation of these reflection fractions for incident QL, QST , and QFT waves show that these fractions depend upon the orientation of the reflecting plane, the plane containing the incident and reflected waves, the angle of incidence, and the elastic constants of the material. When the incident wave is transversely polarized and incident angles exceed critical values there appears to be no analytic solution for the reflection fractions for the reflected bulk elastic waves.
