waves
| Question | Answer |
|---|---|
| wave | traveling disturbance Carrington energy from one place to another |
| vibration | movement the follows the same path over and over again |
| medium | material through witch a mechanical wave travels |
| mechanical wave | wave that disturbs a medium |
| electromagnetic wave | wave that consists of electric and magnetic fields and dose not require a medium to exist |
| crest | high point of a wave |
| trough | low point of a wave |
| amplitude | greatest distance from the resting point of a wave |
| wave length | distance between two consecutive points on a wave |
| frequency | number of waves that pass a certain amount in a given time |
| transverse wave | wave in witch the motion of the medium is at right angles to the direction of the wave |
| longitudinal wave | wave in witch the motion of the wave is parallel to the direction of the wave |
| surface wave | wave that consists of a combination of transverse and longitudinal waves |
| compression | squeezing together |
| reflection | bouncing back of waves reaching another surface |
| refraction | bending of waves due to the change in speed |
| diffraction | bending of waves around an obstacle |
| interference | interaction of waves that occur at the same place at the same time |
| standing wave | wave that dose not occur to be moving |
| resonant frequency | frequency at witch a standing wave occurs |
