|---|---|
| Compression - | region of a longitudinal wave where the particles in the medium are closest together |
| Crest | highest point on a transverse wave |
| Electromagnetic wave | can travel through empty spaces and through matter |
| Energy | ability to cause change |
| Longitudinal wave | makes the partial in a medium move parallel to the direction of the wave |
| mechanical wave | travels only through matter |
| Medium | materials in which a mechanical wave travels |
| transverse wave | disturbance is perpendicular to the direction of the wave |
| trough | lowest point on a transverse wave |
| wave | disturbance that transfers energy from one place to another |
| Amplitude | maximum distance particles in medium move from their rest posotuon as waves pass through the medium |
| frequency | number of wavelength that passes by a point each second |
