waves
| Question | Answer |
|---|---|
| Wave | traveling disturbance that travels from one place to another |
| vibration | Movement thagtg follows the same path over and over again |
| medium | Material through which a mechanical wave travels through |
| mechanical wave | Wave that disturbs a medium |
| electromagnetic wave | Wave that consists of electromagnetic fields |
| crest | high point in a wave |
| trough | low point in a wave |
| Amplitude | is the maximum distance a wave’s particles move from their rest (middle) position. |
| wavelength | is the distance between two identical points on a wave that repeat. |
| frequency | is how many waves pass a point each second. |
| transverse wave | is a wave where the particles of the medium move at right angles (perpendicular) to the direction the wave travels. |
| Longitudinal wave | is a wave in which the particles of the medium move back and forth (parallel) to the direction the wave travels. |
| Surface wave | is a wave that travels along the boundary (surface) between two different media, such as water and air. |
| compression | a compression is the region where the particles of the medium are closer together than normal. |
| reflection | is when a wave bounces off a surface instead of passing through it. |
| refraction | is the bending of a wave as it passes from one medium to another (or when the speed of the wave changes within a medium). |
| diffraction | is the spreading out of waves as they pass through a narrow opening or around an obstacle. |
| interference | is what happens when two or more waves meet in the same place at the same time and combine. |
| standing wave | is a wave that looks like it is not moving along the medium, even though the wave energy is still moving. |
| resonant frequency | is the natural frequency at which an object or system vibrates most easily and with the largest amplitude. |
