- Sound waves can interfere
- Constructive- they bounce up, two crests
- Destructive- they bounce out, one crest and one trough
- Anti-nodes- the point in the middle with no motion
- Sound Waves have basic boundary behavior
- Reflection- bounce back
- Refraction- wave changes direction
- Diffraction- waves bend around objects
