- 5. the distance from one crest to another
- 7. a high point
- 8. a wave that moves matter parallel to the direction of the wave
- 10. the material a wave travels through to transport energy
Down
- 1. a high-density area in a longitudinal wave
- 3. the distance from the rest position to the crest/trough
