Across
  1. 1. an empty space
  2. 5. used to measure sound intensity
  3. 6. the highest point, or peak, of a wave
  4. 7. bending of a wave as it enters a new medium at an angel other than 90 degrees
  5. 10. wave that travels in the same direction as the disturbance
  6. 16. increasing of the strength of an electrical signal
  7. 17. the meeting an combining of waves
  8. 19. highness or lowness of sound
  9. 20. the change in perceived pitch that occurs when the source or the receiver of a sound is moving
  10. 23. strengthening of a sound wave in this way
  11. 26. one complete wave, or cycle, per second
Down
  1. 2. any substance that a wave moves through
  2. 3. bouncing back of a wave after it strikes a barrier
  3. 4. disturbance that transfers energy from one place to another
  4. 8. sound waves in the range above 20,000 hertz
  5. 9. waves that transfer energy through matter
  6. 11. direction in which the wave travels is perpendicular, or at right angles, to the direction of disturbance
  7. 12. the spreading out of waves through an opening or around the edge of an obstacle
  8. 13. for a transverse wave is the distance between a line through the middle of a wave and crest or trough
