what is it called when a seismic wave bounces backward when it reaches a boundary?

Explanation:

In the context of seismic waves (a topic in Physics, a subfield of Natural Science), when a wave hits a boundary and bounces back, this phenomenon is called reflection. Seismic wave reflection occurs as the wave encounters a change in the medium (like different rock layers), causing it to return towards its source.

Answer:

Reflection
