Across
- 3. area of longitudinal wave where the coils are close together
- 4. time
- 6. when 2 waves cancel each other out by being opposites
- 7. point of no motion
- 9. the number of times something occurs in a given period of time
- 11. a wave which doesn't need a medium to travel
- 14. distance between neighboring crests
- 16. particles spread apart in a longitudinal wave
- 17. magnitude of displacement from origin
- 18. waves move the medium parallel to the direction in which the waves travel
Down
- 1. 2 waves combined by adding their displacement together
- 2. the motion of the medium is perpendicular to the direction of the wave
- 5. lowest point of a wave
- 8. highest point on a wave
- 10. waves that require a medium
- 12. the material which a wave travels through
- 13. some points remain fixed, some vibrate
- 15. position of maximum displacement
