Across
  1. 4. wave that can only travel through a medium
  2. 6. one element of a digital picture
  3. 7. specifically designed transparent fiber that transmits light over long distances by total internal reflection
  4. 12. rate of something that repeats over and over
  5. 13. substance or material
  6. 14. changing of a wave's speed and direction as it travels into a medium
  7. 16. a wave bends so much at the interface that it reflects back into the original medium
  8. 17. process of changing the amplitude of a carrier wave to transmit information
Down
  1. 1. bouncing back of waves off an object
  2. 2. length of one wave; the distance from one crest to the next
  3. 3. data expressed as single digits, usually 0 and 1
  4. 5. range of all different wavelengths that can and cannot be seen by the human eye
  5. 8. wave's medium is perpendicular to the movement of the wave traveling through a medium
  6. 9. process of changing the frequency of a carrier wave to transmit information
  7. 10. wave's medium is compressed in the same direction as the movement of the wave
  8. 11. clarity of detail in an image
  9. 15. the height of the peaks above the resting line in a wave
