- 6. when a wave bounces back
- 10. distance between two corresponding parts of a wave
- 11. particle in this wave move perpendicular and parallel to direction of wave
- 12. lowest point of a wave
- 15. interference that makes a bigger wave
- 16. interference that makes a smaller wave
- 18. time it takes for one wave cycle
- 20. this wave needs a medium
- 21. observed change in frequency when source or observer is moving
Down
- 1. two or more waves make one

- 4. medium moves perpendicular to wave
- 7. wave height
- 8. wave bending as it moves around an obstacle
- 9. medium moves parallel
- 13. number of waves that pass a point in a given time
- 14. results from interference between a wave and its reflection
- 17. wave bending as it passes from one medium to another
- 19. a disturbance that transfers energy through matter or space
