| Term | Definition |
|---|---|
| Diffraction | The change in direction of a wave when it encounters an obstacle |
| Refraction | The bending of waves as they pass from one medium to another at an angle |
| Standing wave | A pattern of vibration that resembles a stationary wave |
| Reflection | the bouncing of a wave when it meets a surface or boundary |
| Constructive interference | Interference that increases the amplitude |
| Destructive interference | Interference that decreases the amplitude |
| principle of superposition | sound that produced by interference of sound waves that are used to tune piano strings |
| Beats | point in a standing wave that has no vibration due to destructive interference |
| Interference | The combination of two or more waves that result in a single wave |
| Nodes | Method of adding crest and troughs waves together to describe a new wave |
