| Term | Definition |
|---|---|
| Wave | A disturbance that carries energy from one place to another |
| Medium/Matter | Material that carries a wave (ex. solid, liquid, gas) |
| Compressional Wave/Longitudinal Wave | Medium moves parallel to energy (ex. sound waves) |
| Mechanical Wave | Waves that require a medium to travel through |
| Transverse Wave | Medium moves perpendicular to energy (ex. light waves) |
| Crest | High point of transverse wave |
| Trough | Low point of transverse wave |
| Amplitude | Height from line of rest to either crest or trough |
| Rest | Imaginary line that indicates where a transverse wave would be at rest. |
| Compression | High density area of a compressional wave. Wave is bundled close together. |
| Rarefaction | Low density area of a compressional wave. Wave is spread apart |
| Wavelength | The distance on one part of the wave to another part. (ex. crest to crest, compression to compression) |
| Electromagnetic Wave | Does NOT require a medium to travel. (ex. radio waves phone signals)- can travel through space! |
| Frequency | How many waves pass by in a specific amount of time. Measured in Hetz (Hz) |
