| wave | Any disturbance in matter that transmits energy |
| medium | Any substance through which a wave can travel |
| mechanical | Waves that require a medium are classified as ____ waves. |
| electromagnetic | Waves that don’t need a medium to transfer energy are called __ waves. |
| perpendicular | If the angle between to lines is 90o, the lines are said to be |
| rarefaction | A section of a longitudinal wave where the particles are less crowded than normal is called a |
| amplitude | The maximum distance the wave vibrates from the rest position |
| wave speed | The rate at which a wave travels |
| constructive interference | Occurs when the crests of one wave overlaps the crest of another and theamplitude increases. |
| resonance | The frequency at which a standing wave is produced |
| transverse | Waves in which the particles move perpendicular to the wave energy |
| trough | The lowest point of a transverse wave |
| surface | Waves that occur at or near the boundary between two media form __ waves. |
| compression | A section in a longitudinal wave where the particles are crowded together |
| wavelength | The distance between two corresponding crests or troughs in a series of waves |
| frequency | The number of waves produced in a given amount of time |
| refraction | The bending of a wave as it passes at an angle from one medium to another |
| longitudinal | Waves in which the particles move back and forth in the same direction as the energy are called ___ waves. |
