| Question | Answer |
|---|---|
| wave | traveling disturbance that carries energy |
| vibration | movement that follows the same path over and over |
| medium | material through which a mechanical wave travels |
| 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 a wave |
| trough | low point of a wave |
| amplitude | greatest distance from resting position of a wave |
| wavelength | distance between two consecutive similar points on a wave |
| frequency | number if waves that pass a certain point in a given amount of time |
| transerve wave | wave in which the motion of the medium is at right angles to the direction of the wave |
| longitudinal wave | wave in which the motion is parallel to the direction of the wave |
| surface wave | wave that consists of a combination of transerve waves and longitudinal wave and occurs at the surface |
| compression | squizzing together |
| reflection | bouncing back of waves upon reaching under the surface |
| refraction | bending of waves due to change in speed |
| diffraction | bending of waves around edge of an object |
| interference | interferenc eof waves that occur at the same place and same time |
| standing wave | wave that does not appear to be moving |
| resonant frequency | frequency that a standing wave occurs |
