waves
I <3 Mr Hanson class
| Question | Answer |
|---|---|
| Wave | A wave is a disturbance that moves from the point of origin to another |
| vibration | movement that follows the same pattern over and over again |
| medium | material which a mechanical wave passes through |
| mechanical wave | wave that disturbs a medium |
| electromagnetic wave | wave that consists of electric and magnetic fields and does not require a medium to exist |
| crest | high point of wave |
| trough | low point of wave |
| amplitude | greatest distance from resting position of wave |
| wavelength | distance between two consecutive waves similar point of wave |
| frequency | number of waves that passes a certain point in a given amount of time |
| transverse wave | wave in which the motion of the medium is at a right angle to the direct of the wave |
| longitudinal wave | wave in which the motion of the medium is parallel to the direction of a wave |
| surface wave | wave that consists of a combination of transverse waves and longitudinal waves and occurs at the surface between two different mediums |
| reflection | bouncing back of waves reaching another surface |
| refraction | bending of waves due to speed |
| interference | interaction of waves that occur at the same place and time |
| standing wave | wave that does not appear to be moving occurs at the natural frequency of the material |
| resonant frequency | frequency at which the standing wave occurs |
