Reflection and Refraction of Bulk Waves
- 316 Downloads
When an incident bulk wave interacts with an interface, such as the boundary between a fluid and a solid, as found in immersion testing, both reflected and transmitted bulk waves are generated. Chapter 6 describes general properties of reflected and refracted waves for the case when a planar wave is incident on a plane interface. In the process a variety of concepts are introduced, such as acoustic impedance, Snell’s law, critical angles, pulse distortion, and inhomogeneous waves.
