  1. 3. The rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light)
  2. 4. The act of compressing or the state of being compressed
  3. 7. A wave that moves the medium in a direction perpendicular to the direction in which the wave travels.
  4. 9. A disturbance that travels through space and matter transferring energy from one place to another
  5. 11. The substance or material that carries a wave
  6. 13. The lowest point of a wave
  7. 15. An instance of vibrating
Down
  1. 1. The combination of two or more electromagnetic waveforms to form a resultant wave in which the displacement is either reinforced or canceled
  2. 2. A wave that propagates through a medium due to the oscillation of matter
  3. 5. A point along a standing wave where the wave has minimal amplitude
  4. 6. The reduction of an item's density, the opposite of compression
  5. 8. The distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
  6. 10. The maximum extent of a vibration or oscillation, measured from the position of equilibrium
  7. 12. The high point of a wave
  8. 14. Wave A wave in which the medium moves in the same direction as the wave
