Across
  1. 2. the part in a longitudinal wave where the particles are spread apart
  2. 3. the part of a longitudinal wave where the particles of the medium are close together
  3. 5. the distance an object travels per unit of time
  4. 9. the height of a wave (measured from rest position)
  5. 11. a type of wave that can move through the vacuum of space
  6. 13. a disturbance that transfers energy from place to place
Down
  1. 1. a type of wave that moves the medium in a direction perpendicular to the direction in which the wave travels
  2. 4. (2 words) the position where the wave is at rest, half way between the crest and trough (the medium shows no disturbance here)
  3. 6. the number of complete wavelengths that pass a point in a given time
  4. 7. a type of wave in which the vibration of the medium is parallel to the direction the wave travels
  5. 8. type of wave that requires a medium through which to travel
  6. 10. the distance between two corresponding parts of a wave
  7. 12. the unit of frequency, equal to one complete wave per second
