There are different types of boundary waves, depending on the materials involved and the type of wave:
* Reflected wave: This is a wave that bounces back from the boundary.
* Transmitted wave: This is a wave that passes through the boundary into the second material.
* Surface wave: This is a wave that travels along the boundary between two materials. Examples include water waves and seismic waves.
* Evanescent wave: This is a wave that decays exponentially in the second material.
The specific name for the boundary wave will depend on the specific context. For example, a wave reflecting off a mirror would be called a reflected light wave.
