Across
- 5. — Region in a longitudinal wave where particles are spread far apart
- 6. — Type of wave where particles vibrate parallel to the direction of energy transfer
- 8. — Region in a longitudinal wave where particles are close together
- 13. — Waves that can travel through a vacuum without any medium
- 14. — Bending of a wave when it moves from one medium to another
- 15. — Perception of how high or low a sound is based on frequency
- 17. SPEED — Speed at which energy is carried forward by the wave
- 19. — Distance between two consecutive identical points on a wave
Down
- 1. — Wave that requires a medium to travel
- 2. — Material through which a wave travels
- 3. — Number of complete waves passing a point in one second
- 4. — Type of wave where particles vibrate perpendicular to the direction of energy transfer
- 7. — Occurs when two waves combine to form a larger amplitude
- 9. — Lowest point of a transverse wave
- 10. — Maximum displacement of a particle from its resting position
- 11. — Returning or bouncing back of a wave after hitting a surface
- 12. — Ability of waves to bend around obstacles or spread through openings
- 16. — The highest point of a transverse wave
- 18. — Time taken for one complete wave cycle to pass a point
