waves
| Question | Answer |
|---|---|
| wave | traveling disturbance that carries energy |
| vibration | movement that follows the same path over and over again |
| medium | material through which a mechanical wave travels |
| mechanical wave | wave that disturbs a medium |
| electromagnetic wave | waves that consist of electric and magnetic fields and does not require a medium |
| crest | high point of a wave |
| through | low point of a wave |
| amplitude | greatest distance from resting petition of a wave |
| wavelength | distance between two same points on a wave like crest to crest |
| frequency | number of wave that pass a certain point in a given amount of time |
| transverse wave | wave in which the motion of the medium in 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 | wave at the top of the medium |
| compression | squeezing together |
| reflection | bouncing back of waves upon reaching another surface |
| refraction | bending of waves due to a change in speed |
| diffraction | bending of waves around the edge of an obstacle |
| inference | interaction of waves that occurs at the same time |
| standing wave | wave that does not appear to be moving |
| resonant frequency | frequency at which a standing wave occurs. |
