Across
  1. 4. the distance between the line of equilibrium and the highest or lowest point of a wave
  2. 6. the distance between two crests or two troughs
  3. 7. the bending of a wave as it moves around an obstacle or passes through a narrow opening
  4. 9. material through which a wave transfers energy
  5. 11. the interaction of two or more waves that combine in a region of overlap
  6. 12. waves medium vibrates perpendicular to the direction of the wave
  7. 14. interference combines the energies of two waves interacting into a greater amplitude
  8. 17. wave medium moves in the same direction as the wave's motion
  9. 18. region in a longitudinal wave where the particles are closest together
  10. 19. bending of waves when passing from one medium to another
Down
  1. 1. when a wave strikes an object and bounces off
  2. 2. the highest point of a wave (above the line of equilibrium)
  3. 3. waves waves that must travel through a medium
  4. 5. a region in a longitudinal wave where the particles are furthest apart
  5. 8. number of waves passing a point in one second
  6. 10. waves waves that do not require a medium
  7. 13. interference reduces the energies of two waves interacting into a smaller amplitude
  8. 15. effect a change in wave frequency caused by movement of sound source, motion of the listener, or both
  9. 16. rhythmic disturbances that carry energy through matter or space
  10. 20. the lowest point of a wave (below the line of equilibrium)
