Across
  1. 1. A wave in which the disruptions move perpendicular to the direction of wave travel.
  2. 3. A region of high density and pressure in a longitudinal wave.
  3. 4. The combining of waves where they overlap.
  4. 7. The perceived change in the frequency of a wave due to the motion of the wave’s source or of the receiver.
  5. 8. The maximum displacement from the equilibrium position during periodic motion
  6. 9. The lowest point of a wave.
  7. 12. Motion that repeats in equal time intervals.
  8. 13. The number of waves or cycles that occurs per second.
  9. 16. A wave that is moving even though the locations of the crests and troughs appear to be stationary.
  10. 17. Periodic motion that is caused by a restoring force that is proportional to the displacement of the system.
  11. 20. Reducing the amplitude of periodic motion by applying a force that works against motion.
  12. 21. A disruption that carries energy from one location to another.
Down
  1. 2. The bouncing of waves off a surface.
  2. 3. The highest point of a wave.
  3. 5. A region of lower density and pressure in a longitudinal (compression) wave.
  4. 6. An increase in the amplitude of a vibration due to additional wave input.
  5. 10. The bending of waves around an obstacle or through an opening.
  6. 11. A wave that carries energy through a physical medium.
  7. 14. A wave in which the disruptions are parallel to the direction of wave travel.
  8. 15. The time interval for one complete cycle of periodic motion.
  9. 18. A change in wave direction due to a change in a wave’s speed as it enters a new medium.
  10. 19. The distance between two identical points on successive waves.
