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