Across
  1. 2. The displacement of the particles of the medium is perpendicular to the direction of the wave
  2. 4. the point on the medium that exhibits the maximum amount of positive displacement from the rest position
  3. 6. unit for frequency
  4. 10. the maximiun displacement of a particle of the medium from the rest
  5. 11. unit for period
  6. 14. a wave that is not capable of transmitting its energy
  7. 15. the time it takes for an object to complete one cycle
  8. 17. the spreading of waves around obstacles
  9. 20. the point on the medium that exhibits the maximum amount of negative displacement from the rest position
Down
  1. 1. the shortest distance between two points
  2. 3. the horizontal line in the middle of the wave.
  3. 5. The number of cycles in one second
  4. 7. a property applying to transverse waves that specifies the geometrical orientation of the oscillations
  5. 8. A disturbance that propagates through a material medium or space
  6. 9. The displacement of the particles of the medium is parallel to the direction of the wave
  7. 12. One repetition of the motion
  8. 13. the pattern of disturbance caused by the movement of energy traveling through a medium
  9. 16. system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration
  10. 18. the change in direction of a wave passing from one medium to another caused by its change in speed.
  11. 19. a longitudinal wave propagated by the elastic compression of the medium
