Waves

3. length of one wave; the distance from one crest to the next
4. rate of something that repeats over and over
7. wave that can only travel through a medium
9. a wave bends so much at the interface that it reflects back into the original medium
11. process of changing the amplitude of a carrier wave to transmit information
13. data expressed as single digits, usually 0 and 1
15. wave's medium is compressed in the same direction as the movement of the wave
16. changing of a wave's speed and direction as it travels into a medium
17. bouncing back of waves off an object

1. substance or material
2. clarity of detail in an image
5. range of all different wavelengths that can and cannot be seen by the human eye
6. process of changing the frequency of a carrier wave to transmit information
8. the height of the peaks above the resting line in a wave
10. specifically designed transparent fiber that transmits light over long distances by total internal reflection
12. one element of a digital picture
14. wave's medium is perpendicular to the movement of the wave traveling through a medium
