Across
  1. 3. transfer any form of energy, sound wave, light, and heat
  2. 6. the flow of energy at the speed of light
  3. 8. all points oscillate to the direction of the waves advance
  4. 13. distance between origin and crest
  5. 14. when two waves add together so that the amplitude of the resulting wave is equal to the sum of the individual amplitudes
Down
  1. 1. difference between the frequency at which sound or light waves leave a source
  2. 2. the range of all types of EM radiation
  3. 4. abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums
  4. 5. the distance a wave travels in a certain time
  5. 7. number of waves produced in a certain amount of time
  6. 9. the spreading of waves around obstacles
  7. 10. a positive displacement of one wave is cancelled exactly by a negative displacement of the other wave
  8. 11. same direction as the direction of the travel of the wave
  9. 12. the distance between identical points
  10. 15. the change in direction of a wave passing from one medium to another caused by its change in speed
