Across
- 3. distance between the crest and the equilibrium
- 8. a wave that vibrate perpendicular to the direction
- 9. time for one complete wave
- 10. highest point in the upward displacement
- 11. gives weight to an object
Down
- 1. distance between two consecutive crests
- 2. weight may vary but this never changes
- 4. a wave that vibrate parallel to the direction
- 5. an example of a longitudinal wave
- 6. number of waves per unit time
- 7. the pull of gravity
- 12. lowest point in the downward displacement
