Across
  1. 2. the rate at which a wave’s energy flows through a given area
  2. 4. area where the particles in a medium are spaced close together
  3. 6. a unit that compares the intensity of different sounds
  4. 9. = Wavelength × Frequency
  5. 11. the bending of a wave as it moves around an obstacle or passes through a narrow opening
  6. 17. a change in sound frequency caused by motion of the sound source
  7. 20. a wave that causes the medium to vibrate at right angles to the direction in which the wave travels
  8. 21. motion that repeats at regular time intervals
  9. 22. physical response to the intensity of sound, modified by physical factors
  10. 23. lowest point of the wave
  11. 25. the distance between a point on one wave and the same point on the next cycle of the wave
  12. 26. a technique for determining the distance to an object under water
Down
  1. 1. a wave that travels along a surface separating two media
  2. 3. occurs when a wave bounces off a surface that it cannot pass through
  3. 5. is a disturbance in matter that carries energy from one place to another.
  4. 7. a wave in which the vibration of the medium is parallel to the direction the wave travels
  5. 8. the bending of a wave as it enters a new medium at an angle
  6. 10. the frequency of a sound as you perceive it
  7. 12. the maximum displacement of the medium from its rest position
  8. 13. sound at frequencies higher than most people can hear
  9. 14. time required for one cycle, a complete motion that returns to its starting point
  10. 15. sound at frequencies lower than most people can hear
  11. 16. area where the particles in a medium are spread out
  12. 18. the number of complete cycles in a given time
  13. 19. highest point of the wave
  14. 24. cycles per second
