WAVES
| Term | Definition |
|---|---|
| wave | a disturbance that transfers energy from place to place |
| amplitude | the maximum distance the particles of a medium move away from the rest positions as a wave passes through the medium |
| frequency | the number of complete waves that pass a given point in a certain amount of time |
| wavelength | the distance between two corresponding parts of a wave |
| energy | the ability to do work |
| mechanical wave | a wave that requires a medium through which to travel |
| reflection | the bouncing back of an object or a wave when it hits a surface through which it cannot pass |
| refraction | the bending of waves as they enter a new medium at an angle |
| crest | the highest part of a transverse wave |
| trough | the lowest part of a transverse wave |
| medium | the material through which a wave travels |
| transverse wave | a wave that moves the medium in a direction perpendicular to the direction in which the wave travels |
| longitudinal wave | a wave that moves the medium in a direction parallel to the direction in which the wave travels |
