Across
- 5. any motion that repeats at regular time intervals
- 6. an indication of how high or low a sound is, which is primarily determined by the frequency of the sound wave
- 9. Sound travels fastest in this medium
- 12. threshold of human hearing
- 13. unit for measuring intensity
- 16. A wave in which the medium vibrates at right angles to the direction the wave travels
- 19. vibrate back and forth
- 22. the rate at which a wave’s energy flows through a given area
- 24. the highest point on a wave
- 25. below the range of human hearing
- 27. the time it takes to complete a full cycle
- 29. Prolonged exposure to loud sounds can destroy the cells in this part of the ear
- 31. stretched out sections of longitudinal waves
- 32. a wave that travels along the surface of a medium
- 33. the distance between two adjacent crests or two adjacent troughs
Down
- 1. the height of a wave from midpoint to crest or midpoint to trough
- 2. the lowest point on a wave
- 3. the number of complete cycles (crest to crest or trough to trough) in a given time
- 4. a wave in which the vibration of the medium is parallel to the direction the wave travels
- 7. Greek letter λ
- 8. Traveling Faster than the Speed of Sound
- 10. compressed sections of longitudinal waves
- 11. wavelength x frequency
- 14. SI unit for frequency
- 15. a disturbance in matter that transfers energy through the matter (a medium)
- 17. a thunder-like sound produced as a result of an object traveling at or above Mach 1
- 18. can be a solid, liquid, or gas
- 20. sound navigation and ranging
- 21. beyond the range of human hearing
- 23. unit for supersonic speed
- 26. ringing in the ears
- 28. A change in sound frequency caused by the motion of the sound source, motion of the listener, or both
- 30. Unit for measuring temperature
