  3. 11. Waves that can travel through an empty space
  4. 12. A disturbance that travels through a medium from one location to another location
  5. 13. The change in direction of a wavefront at an interface between two different media so that it returns to the medium from which it came
  6. 14. Occurs when waves bend around small obstacles, or when waves spread out after they pass through small openings
  7. 16. The storing of energy
  8. 17. Any substance that carries the wave, or through which the wave travels
  9. 19. A point on the wave where the displacement of the medium is at a maximum
  10. 20. wave A wave vibrating at right angles to the direction of its propagation
Down
  1. 1. The frequency of a sound wave
  2. 2. Waves where the disturbance moves in the same direction as the wave
  3. 4. The entire range of electromagnetic waves from low to high frequency
  4. 5. The number of waves that pass a fixed point in unit time
