Across
  1. 7. a material through which a wave travels
  2. 10. a disturbance in matter that carries energy from one place to another
  3. 11. the bending of a wave as it enters a new medium at an angle
  4. 14. an area of a longitudinal wave where the particles of the medium are spread out
  5. 15. the maximum height of a wave
  6. 16. the highest point of a transverse wave
  7. 17. the lowest point of a transverse wave
  8. 18. unit used to measure frequency of a wave
Down
  1. 1. a wave that travels along a surface separating two media
  2. 2. a wave that causes the medium to vibrate at right angles to the direction in which the wave travels
  3. 3. an area of a longitudinal wave where the particles of the medium are close together
  4. 4. the interaction that occurs when a wave bounces off a surface that it cannot pass through
  5. 5. the distance between a point on a wave and the same point on the next wave
  6. 6. a wave in which the vibration of the medium is parallel to the direction the wave
  7. 8. any motion that repeats at regular time intervals
  8. 9. the bending of a wave as it moves around an obstacle or passes through a narrow
  9. 12. time required for one wave to pass
  10. 13. the number of complete waves that pass per second
