waves
| Question | Answer |
|---|---|
| waves | traveling disturbance that carries energy |
| vibration | movement that follows the same path over and over |
| mechanical wave | wave that disturbs a medium |
| electromagnetic wave | wave that consists of electric and magnetic fields |
| 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 of waves that pass a certain point in a given amount of time |
| transverse 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 of the medium is parallel to the direction of the wave |
| surface wave | occurs at the top of a wave |
| compression | squeezing together |
| reflection | bouncing back of waves reaching another surface |
| refraction | bending of waves due to a change of speed |
| diffraction | bending of waves around the edge of an obstacle |
| interference | interaction of waves that occurs at the same place same time |
| standing wave | wave that does not appear to be moving |
| resonant frequency | frequency at which a standing wave occurs |
