Across
  1. 2. the bouncing back of a wave after it strikes a barrier
  2. 6. the bending of a wave as it enters a new medium at an angle other than 90 degrees
  3. 10. the lowest point or valley of a wave
  4. 12. a disturbance that transfers energy from one place to another
  5. 13. the direction in which the wave travels is perpendicular to the direction of the disturbance
  6. 14. when a 1m wave crest meets a 1m wave trough, the amplitudes cancel each other of to make an amplitude of 0
  7. 16. waves that transfer energy through matter
  8. 17. the distance a medium moves above or below its position of rest
  9. 18. the number of waves passing a fixed point in a certain amount of time
Down
  1. 1. the highest point or peak of a wave
  2. 3. the water or medium level at rest
  3. 4. when two wave crests with amplitudes of 1m each combine to make an amplitude of 2m
  4. 5. a longitudinal wave produced by vibrations
  5. 7. the wave travels in the same direction of the disturbance
  6. 8. the meeting and combining of waves
  7. 9. the distance from one crest or trough to the next
  8. 11. the highness or lowness of a sound determined by the frequency of the sound wave
  9. 12. =wavelength multiplied by frequency
  10. 14. the spreading out of waves through an opening or around the edge of an obstacle
  11. 15. any substance a wave moves through
