The sound strikes the cantina walls and bounces off at the same angle as it struck in a process known as reflection refraction constructive interference destructive interference

Answer;

Reflection

Explanation;Reflection is one of the property of waves that occurs when a wave hits a surface or a boundary and bounces back off back towards the source.\Sound is a mechanical wave, which requires a material medium for transmission. When sound wave is being transmitted it hits or strikes the surface or a boundary and bounces back towards the source in an opposite direction. This is referred to as the reflection of sound waves.Therefore, reflection entails change in direction of a wave upon hitting a surface or a boundary, such that it returns to the source of origin.
