|---|
| transverse | waves w/ particles that vibrate perpendicular to the equilibrium position |
| longitudinal | waves w/ particles that vibrate in the direction of the wave energy |
| crest | top point of a transverse wave |
| trough | bottom point of a transverse wave |
| wavelength | distance from crest to crest or trough to trough |
| amplitude | wave height from equilibrium position |
| frequency | # of waves that pass a point in 1 second |
| Hz (Hertz) | unit of measure for wave frequency |
| rarefaction | area in a compressional (longitudinal) wave where particles are far apart |
| compression | area in a longitudinal wave where particles are close together |
