The velocity of sound in each material is determined by the material properties (elastic modulus and density) for that material. In the animation below‚ a series of plane waves are shown traveling in one material and entering a second material that has a higher acoustic velocity. Therefore‚ when the wave encounters the interface between these two materials‚ the portion
