| wave | traveling disturbance that carries energy from one place to another |
| longitudinal wave | wave in which the motion of the medium is parallel to the direction of the wave |
| surface wave | wave that consists of a combination of transverse and longititudinal waves and occurs at the surface between two differnt mediums |
| reflection | bouncing back of waves upon reaching another |
| refraction | bending of waves due to a change in speed |
| diffraction | bending of waves around the edge of an obstacle |
| interference | interaction of waves that occur at the same place at the same time |
| standing wave | wave that does not appear to be moving |
| resonant frequency | frequency at which a standing wave occurs |
