| Question | Answer |
|---|---|
| waves | a disturbance or variation that transfers energy progressively from point to point in a medium |
| 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 | wave that consists of electro and magnetic field (doesn't need a medium) |
| crest | high point of wave |
| trough | low point of a wave |
| amplitude | greatest distance from resting point of wave |
| wavelength | distance between 2 consecutive similar point on a wave |
| frequency | number of waves that pass a certain point in given 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 | wave that consists of a combination of transverse and longitudinal waves and occurs at the surface between 2 other mediums |
| compression | squeezing together |
| reflection | bouncing back of waves upon reaching another surface |
| refraction | bonding of waves due to a change in speed |
| diffraction | bending of waves around the edge of an obstacle due to a change in speed |
| interference | interaction of waves that occur at the same place at the same time |
| standing wave | wave that doesnt appear to be moving |
| resonant frequency | frequency at which a standing wave occurs |
