Across
- 1. The number of oscillations per unit time
- 3. The highest point of a wave
- 5. Effect related change in wave frequency
- 7. The region in a longitudinal wave where particles are closest together
- 9. The distance between two consecutive crests of a wave
- 14. When two waves overlap
- 16. Area where particles are spread apart
- 17. Regular back and forth motion of waves
- 18. The lowest point in a wave
- 20. Mechanical waves that travel through air, water, and solids, allowing us to hear sounds/
Down
- 2. Wave Wave that does not require a medium (light, radio waves)
- 4. Wave Wave where particles move perpendicular to the direction of travel
- 6. Bending of waves due to change in speed
- 8. The normal position of the medium when no wave is present
- 10. Speed The speed at which energy travels through a medium
- 11. Spreading of waves around obstacles
- 12. When a wave bounces off a surface
- 13. The time it takes for one complete wave cycle
- 15. Wave Wave where particles move parallel to the direction of travel
- 19. Wave Wave that requires a medium (sound, water waves)
