| amplitude | greatest distance from crest of a wave |
| crest | hight point of a wave |
| diffraction | bending of waves around the edge of an obstacle |
| electromagnetic wave | wave that consists of electric and magnetic fields and does not require a medium to exist |
| frequency | number of waves that pass a certain point in a given amount of time |
| interference | interaction of waves that occur at the same place at the same time |
| longitudinal wave | wave in which the motion of the medium is parallel to the direction of the wave |
| mechanical wave | a wave that disturbs a medium |
| medium | material through which a mechanical wave travels |
| reflection | bouncing back of waves upon reaching another surface |
| refraction | bending of waves due to a change in speed |
| resonant frequency | frequency at which a standing wave occurs |
| standing wave | wave that does not appear to be moving, occurs at the natural frequency of the material |
| surface wave | wave that consists of transverse and longitudinal waves and occurs at the surface between two different mediums |
| transverse wave | wave in which the motion of the medium is at right angles to the direction of the wave |
| trough | lowpoint of a wave |
| vibration | movement that follows the same path over and over again |
| wave | traveling disturbance that carries energy from one place to another |
| wavelength | distance between two consecutive similar points on a wave |
