EFFECT OF THE SPHERICITY OF AN ACOUSTIC-WAVE ON ITS REFLECTION FROM APLANE INTERFACE BETWEEN 2 FLUIDS

The effect of the sphericity of an acoustic wave on its reflection fro m a plane boundary between two liquid media is investigated in a situa tion when the reflection coefficient can change its sign in reflection . An exact solution is presented as a real-valued integral over a fini te path, which is convenient for computations. The reflection coeffici ent calculated as a function of time is plotted for various media. For mulas obtained in this paper together with those presented in our prev ious work [12] are used to calculate reflected spherical waves of any form and duration at arbitrary distance from the source and far any pa rameters of contacting liquids.
