Across
  1. 5. a force that "acts perpendicularly on a surface"
  2. 6. 1. Sympathetic 2. Sounding Board and 3. Acoustic Resonance are examples of what type of vibration
  3. 8. Lowest point in a cycle; Max point of rarefaction
  4. 11. Multiple reflections (echo)
  5. 17. Positive pressure; molecules move close together
  6. 19. a disturbance (sound source) creates changes in pressure throughout an elastic medium
  7. 20. The kind of sounds periodic and aperiodic are
  8. 21. Disturbance of pressure that moves through a medium
  9. 23. refers to the amount of matter in an object
  10. 24. Distance from crest to crest or trough to trough
  11. 25. Sound passes through something
  12. 28. Branch of physics concerned with the properties of sound
  13. 32. Consist of a series of frequencies that are systematically related to each other
  14. 33. The property of an object to return to its original shape
  15. 35. Unit that measures the intensity of a sound
  16. 37. seconds/cycles
  17. 38. Wave changes direction because of a local difference of temperature in the air
  18. 40. Maximum upward displacement; Max point of compression
Down
  1. 1. In motion stays in motion; At rest stays at rest
  2. 2. Damping of a wave
  3. 3. Resonance also Acoustical Resonance
  4. 4. Some portion of the sound wave that is not transmitted or absorbed bounces back from the surface of the boundary; traveling in opposite direction
  5. 7. Harmonic Motion A smooth back and forth motion
  6. 9. A vibratory response to an applied force
  7. 10. Pressure Pressure at sea level
  8. 12. Lower pressure; molecules move farther apart
  9. 13. Wave changes direction due to an obstacle
  10. 14. Pressure Pressure above the atmospheric pressure
  11. 15. Vibration occurring from a point of rest to max. displacement to rest to mac displacement; one compression and one rarefaction
  12. 16. Something that is set into vibration by the action of another vibration
  13. 18. Frequency Lowest Frequency
  14. 22. 2 or more frequencies but the frequencies are not systematically related to each other
  15. 26. Max. displacement from position of rest; Perception of loudness
  16. 27. Decrease in amplitude
  17. 29. Wave given their name due to the appearance that they are "stationary"
  18. 30. Cycles/Seconds
  19. 31. The quantity of a three-dimnesional shape occupied by a liquid, solid, or gas
  20. 34. Pressure Pressure below atmospheric pressure
  21. 36. Law Volume and pressure are inversely related
  22. 39. any influence that causes an object to undergo a change in speed, direction, or shape
