Across
  1. 2. an increase or decrease in the frequency of different mediums
  2. 4. synchronous vibration of a neighboring object.
  3. 6. change in direction of a wavefront
  4. 9. oscillations are parellel to the direction of the wave's advance.
  5. 10. combination of two waves
  6. 13. a cycle per second; one hertz.
  7. 15. the displacement of the wavelength
  8. 16. waves is spread out as a result of passing through a narrow aperture
  9. 17. The time it takes for two complete wavelength
  10. 18. through the interface between one medium to another
  11. 19. a substance or material that carries the wave
  12. 20. the distance from one crest to another
Down
  1. 1. unit of frequency
