Across
  1. 3. The perception of how high or low a sound is
  2. 4. This phenomenon occurs when a wave bounces off a surface
  3. 7. Sound waves reflect to produce
  4. 10. The perception of the amplitude of a sound wave
  5. 13. Type of wave in which the vibrations are at right angles to the direction of wave propagation
  6. 15. When waves interact, this principle is used to find their total displacement
  7. 16. This parameter of a wave does not change as the wave moves from one medium to another
  8. 17. A disturbance that transfers energy from place to place
  9. 18. These waves can travel in a vacuum
  10. 20. The point on a wave where maximum upward displacement from the rest position is exhibited
  11. 21. This type of interference will occur if two waves are in antiphase
  12. 25. These waves require a medium for their propagation
  13. 26. These electromagnetic waves have the shortest wavelength
  14. 29. These electromagnetic waves have the longest wavelength
  15. 30. This wave is caused by vibrations that are transmitted through matter and it is an example of a longitudinal wave
Down
  1. 1. These waves contain nodes and antinodes
  2. 2. Type of wave that transfers energy from a point source to the surrounding area
  3. 5. The distance between successive corresponding points on a wave
  4. 6. When this type of interference occurs the wave amplitude increases
  5. 8. The region of a medium through which a longitudinal wave is traveling that has the maximum density
  6. 9. A space void of matter
  7. 11. We hear sound from an adjacent room because of this phenomenon
  8. 12. Wave sources that have the same frequency and constant phase relationship
  9. 14. The change in direction of a wave passing from one medium to another caused by its change in speed
  10. 16. The wave parameter that indicates the number of complete waves that pass a given point in unit time
  11. 19. The point on a wave where maximum downward displacement from the rest position is exhibited
  12. 22. The part of a longitudinal wave where the particles of the medium are far apart
  13. 23. This wave parameter gives the distance travelled by a point on a wave in unit time
  14. 24. Type of wave in which the displacements are parallel to the direction of energy transfer
  15. 27. The maximum displacement from the rest position; gives an indication of the amount of energy transported by a wave
  16. 28. The time it takes for one cycle of a wave to travel
