Waves
the study of waves and their properties
| Term | Definition |
|---|---|
| wave | a disturbance, oscillation, or vibration that travels through space and time, transferring energy from one location to another without transferring matter |
| mechanical wave | disturbances or oscillations that transfer energy through a physical medium (solid, liquid, or gas) without transporting matter |
| medium | a substance—solid, liquid, gas, or plasma—that carries or propagates energy, waves, or signals from one location to another |
| transverse wave | a type of wave where the disturbance or oscillation occurs perpendicularly (at a right angle) to the direction of energy transfer |
| longitudinal wave | a mechanical wave where particles of the medium vibrate parallel to the direction of energy transfer, creating alternating regions of high-density compression and low-density rarefaction |
| sound wave | a wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air. |
| amplify | increase the volume of (sound), especially using an amplifier. |
| frequency | the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second. |
| wavelength | the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave. |
| pitch | a persuasive presentation (sales pitch), the highness/lowness of sound, or throwing/launching something |
