  1. 1. A technology that transmits and receives sound waves to find objects
  2. 4. The number of wave cycles that pass a given point per unit of time
  3. 5. The distance between any two corresponding points on a wave, such as from crest to crest
  4. 6. An amplification in the oscillation of an object that occurs when the object is being vibrated at a particular frequency
  5. 8. Interference when the crest of one wave meets the trough of another wave at the same point, decreasing the wave’s amplitude
  6. 11. When a wave encounters an object in its path and bends around it
  7. 12. Interference when the crest of one wave meets the crest of another wave at the same point, increasing the wave’s amplitude
  8. 14. A rhythmic disturbance that moves through a medium or vacuum
  9. 17. The transfer of energy through matter or space as electromagnetic waves, such as visible light and infrared waves
  10. 19. A denser, tightly compressed region of a longitudinal wave
  11. 21. The material through which a wave travels
  12. 24. A wave that moves in the same direction (parallel) as the displacement of the transmitting medium
Down
  1. 2. Energy waves bouncing off the surface of an object
  2. 3. A wave that moves in a direction perpendicular to the displacement of the transmitting medium
  3. 7. The transfer of energy into a medium
  4. 9. A less dense, more spread-out region of longitudinal waves
  5. 10. The perceived highness or lowness of a sound; the higher the frequency, the higher the pitch
  6. 11. An apparent shift in the frequency of a wave as the observer or source moves toward (or away) from the other
  7. 12. The highest part of a wave
  8. 13. To pass something from one place to another
  9. 15. Energy waves bending (changing direction and speed) as they pass from one type of object to another
  10. 16. A space completely empty of matter
  11. 18. The rate of change of position (or distance traveled) with respect to time
  12. 20. The height of a wave from the origin to the crest
  13. 22. A quality determined by the amplitude of the sound wave; the higher the amplitude, the louder the sound
  14. 23. The lowest part of a wave
