| Term | Definition |
|---|---|
| Wave | is a disturbance that transfers energy from one place to another without transferring matter. |
| Mechanical wave | is a wave that travels only through matter. |
| Medium | a material in which a wave travels |
| Transverse wave | is a wave in which the disturbance is perpendicular to the direction the wave travels. |
| longitudinal wave | cause the particles in a medium to move parallel to the direction that the wave travels. |
| Sound wave | is a longitudinal wave that can travel only through matter |
| Amplitude | of a wave is the maximum distance that the wave moves from its rest position |
| Loudness | is how you perceive the energy of a sound wave. |
| Intensity | is the amount of sound energy that passes through a square meter of space in one second. |
| Wavelength | the distance between one point on a wave to the same point on the next wave |
| Frequency | a wave is the number of time that pattern repeats in a given time. |
| Pitch | the perception of how high or low a sound seems |
| Reflection | is the bouncing of a wave off a surface |
| Absorption | is the transfer of energy by a wave to the medium thorough which it travels |
| Transmission | is the passage of a wave through a medium |
| Diffraction | the change in direction of a wave when it travels by the edge of an object or through an opening |
