| A | B |
|---|
| crest | highest point of transverse wave |
| trough | lowest point of transverse wave |
| wavelength | distance from crest to crest or trough |
| amplitude | distance from rest position to crest or trough |
| rest position | medium before the disturbance occurs |
| medium | material a wave travels through |
| energy | ability to do work |
| mechanical wave | wave that must of a medium to travel |
| transverse wave | wave & energy travel at right angles to the direction medium travels |
| longitudinal wave | wave & energy travel in the same (parallel) direction to the medium |
| surface wave | combination of transverse & longitudinal waves |
