| Question | Answer |
|---|---|
| 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 space and through matter |
| Energy | Ability to cause change |
| Longitudinal wave | Makes the particles in a medium move parallel to the direction of the wave |
| mechanical wave | travels only through water |
| Medium | Material in which a mechanical wave travels |
| Rarefaction | Region of a longitudinal wave where the particles are farthest apart |
| 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 a medium move from their rest position as waves pass through the medium |
| Frequency | number of the wavelengths that pass by a point each second |
| Wavelength | distance From one point on a wave to the same point on the next wave. |
