waves
| Question | Answer |
|---|---|
| waves | traveling disturbance that carries energy from one place to another. |
| vibration | movement that follows the same path over an d over again. |
| medium | material through which a mechanical wave travels |
| mechanical wave | wave that disturbs a medium |
| electromagnetic wave | wave that consist of electric and magnetic fields an does not require a medium to exist |
| crest | high point of the wave |
| trough | low point of the wave |
| amplitude | greatest distance from resting position of a wave |
| wavelength | distance between two consecutive similar points of a wave. |
| frequency | number of waves that pass a certain point is given amount of time |
| transverse wave | wave in which the motion of the medium is at right angels to the direction of the wave |
| longitudinal wave | wave in which the motion of the medium is pulled to the direction of the wave |
| surface wave | wave that consists of a combination of transverse a longitudinal wave and occurs at the surface between two different mediums |
| compression | squeezing together |
| reflection | bouncing back of waves upon reaching another surface |
| refraction | bending of waves due to change in speed |
| diffraction | bending of waves around the edges of an obstacle |
| interference | interaction of waves that occur at the same place at the same time |
| standing wave | wave that does not appear to be moving, occur at the natural frequency of the material. |
| resonate frequency | frequency at which a standing wave occurs. |
