Waves
| Question | Answer |
|---|---|
| Waves | Traveling disturbance that carries energy |
| Vibration | Repeated motions that cause waves |
| Mechanical wave | wave that goes through a medium |
| Electromagnetic wave | wave that does not need a medium |
| medium | material a wave travels through |
| Standing wave | wave that does not appear to be moving |
| crest | top of a wave |
| trough | bottom of a wave |
| wavelength | crest to crest or trough to trough |
| amplitude | distance from rest to crest |
| frequency | number of waves past a point in a given time |
| compression | squeezing together |
| Resonant frequency | frequencty of a standing wave |
| longitudinal wave | wave that'moves parallel to the motion of the wave |
| transverse wave | wave taht moves in right angles to the moti0n of the wave |
| reflection | bouncing of a wave off an object |
| difraction | bending of a wave around an object |
| interference | two waves occuring t the same time |
| refraction | bending of a wave due to a change in speed |
| Surface wave | wave that does not appear to be moving |
