Across
- 3. wave that travels
- 5. needs something to travel through
- 8. overlap in space
- 9. "peak" of a wave
- 11. back and forth
- 13. cancel parts
- 14. where the propagation is periductular to the oscillation
- 16. propagate
- 17. frequency of sound, light, or other waves
- 18. sound produces

Down
- 1. moves from one place to another
- 2. builds up wave energy
- 4. where the propagation is parallel to the medium
