Waves

4. the height of the peaks above the resting line in a wave
6. substance or material
8. a wave bends so much at the interface that it reflects back into the original medium
12. process of changing the frequency of a carrier wave to transmit information
13. wave that can only travel through a medium
15. changing of a wave's speed and direction as it travels into a medium
16. clarity of detail in an image

1. data expressed as single digits, usually 0 and 1
2. wave's medium is compressed in the same direction as the movement of the wave
3. length of one wave; the distance from one crest to the next
5. bouncing back of waves off an object
7. wave's medium is perpendicular to the movement of the wave traveling through a medium
9. range of all different wavelengths that can and cannot be seen by the human eye
10. process of changing the amplitude of a carrier wave to transmit information
11. specifically designed transparent fiber that transmits light over long distances by total internal reflection
12. rate of something that repeats over and over
14. one element of a digital picture
