| Wave | a repeating disturbance that transfers energy |
| vibration | a repeated movement |
| Medium | the matter through which waves move |
| Transverse wave | a wave in which the medium moved at right angles to the direction of the wave |
| Compressional wave | a wave in which the medium moves in the same direction as the wave |
| Crest | The highest point on a transverse wave |
| Trough | the lowest point on a transverse wave |
| Rarefaction | an area of low density in a compressional wave |
| Compression | an area of high density in a compressional wave |
| Wavelength | the distance from one point on a wave to the next point just like it |
| Amplitude | the measure of the energy carried by a wave. |
| Reflection | when a wave’s direction is changed by bouncing off an object |
| Refraction | the bending of a wave as its speed changes when moving through different mediums |
| diffraction | the bending of a wave when it goes around another object |
| interference | when two or more waves overlap and create a new wave. |
| standing wave | are formed when two waves combine and create a pattern that does not appear to move |
| resonance | the ability to absorb energy at a certain frequency |
