4. wave that can only travel through a medium
6. one element of a digital picture
7. specifically designed transparent fiber that transmits light over long distances by total internal reflection
12. rate of something that repeats over and over
13. substance or material
14. changing of a wave's speed and direction as it travels into a medium
16. a wave bends so much at the interface that it reflects back into the original medium
17. process of changing the amplitude of a carrier wave to transmit information

1. bouncing back of waves off an object
2. length of one wave; the distance from one crest to the next

5. range of all different wavelengths that can and cannot be seen by the human eye
8. wave's medium is perpendicular to the movement of the wave traveling through a medium
9. process of changing the frequency of a carrier wave to transmit information
