| Amplitude | the maximum distance the wave vibrates from its rest position |
| Rest position | position where the particles of a medium stay when there is no disturbance |
| Wavelength | the distance between any two adjacent crests, compressions, troughs or rarefactions in a series of waves |
| Frequency | the number of waves produced in a given amount of time |
| Hertz | term used to express frequency |
| Hz | abbreviation for Hertz |
| Wave speed | speed at which a wave travels |
| v=λ x f | formula used to calculate wave speed |
| v | variable used for wave speed |
| λ | variable used for wavelength |
| f | variable used for frequency |
| SONAR | sound navigation and ranging |
| Longitudinal | type of wave in which the particles move back and forth along the path that the wave travels |
| Transverse | type of wave in which the particles vibrate with an up-and-down motion, perpendicular to the direction in which the wave is traveling |
