Across
  1. 1. Horizontal distance between the crests or between the troughs of two adjacent waves, measured in metres(m)
  2. 3. The change in direction of a wave when it travels by the edge of an object or through an opening.
  3. 5. Maximum distance a wave varies from its rest position
  4. 6. A space where no particles of matter exist
  5. 8. The change in direction of a wave that occurs as the wave changes speed when moving from one medium to another.
  6. 9. How many waves can pass a given point per second, measured in Hertz (Hz)
  7. 11. A wave in which the vibration is at right angles to the direction in which the wave is traveling.
  8. 13. A repeated back-and-forth or up-and-down motion
Down
  1. 2. A wave in which the vibration of the medium is parallel to the direction the wave travels
  2. 4. A region of a longitudinal wave where the particles of the medium are closest together.
  3. 7. The bouncing of a wave off a surface.
  4. 10. The highest points on a transverse wave.
  5. 12. The lowest points on a transverse wave.
