Across
- 2. short wavelength/high frequency;flute
- 4. distance between a crest and the next crest, or the trough and the next trough
- 5. A disturbance that transfers energy from place to place
- 8. the lowest point of a wave
- 11. A repeated back-and-forth or up-and-down motion
- 12. sound wave with low amplitude, like a whisper
- 14. highest point of a wave
- 15. how "high" or "low" a sound sounds
- 17. interruption of a state of stillness/quiet
Down
- 1. distance between crest/trough & resting point
- 3. the material through which a wave travels
- 4. vertical distance from the crest of a wave to the trough
- 6. long wavelength and low frequency; tuba
- 7. the number of waves per second
- 9. the medium that waves move slowest through
- 10. sound wave with a high amplitude,like fireworks
- 13. the medium that waves move fastest through
- 16. the visible part of the ear (external ear)
