Across
- 5. The time required for one complete wave cycle
- 8. The spreading of waves when they pass through an opening or around an edge
- 11. The region in a longitudinal wave where particles are spread apart
- 13. The highest point of a wave
- 15. The region in a longitudinal wave where particles are close together
- 16. A wave in which particles move perpendicular to the wave’s direction
- 17. The bouncing back of a wave after hitting a surface
- 18. The increase in amplitude when an object vibrates at its natural frequency
- 19. The bending of a wave as it enters a new medium
- 20. The speed at which a wave travels through a medium

- 22. The lowest point of a wave
Down
- 1. The number of wave cycles that pass a point each second
- 2. The maximum displacement of a wave from its rest position
- 3. A wave in which particles move parallel to the wave’s direction
