Waves

3. Information that has been changed into a form computers can easily use.
5. The part of a wave that is farthest above its resting position.
7. A signal that changes smoothly rather than using separate values.
8. Two ways radio stations can change a wave to carry information.
13. A measurement that can tell you how strong a wave is.
17. The part of a wave that is farthest below its resting position.
18. When a material takes in some of the energy carried by a wave.
19. A wave in which particles move at a right angle to the direction the wave travels.
20. Waves that travel through a body of water and cause particles to move mostly up and down.
22. Thin strands that can use light to carry information over long distances.
24. The number of complete wave patterns that pass a certain location in a given amount of time.
25. The matter that allows certain waves to travel.
26. A wave pattern with one basic repeating shape.
28. Devices that can exchange information without a physical cable by using radio waves.
30. Describes a material that blocks light from passing through.
31. What happens when a wave travels through a material instead of being blocked or bounced back.

1. A repeating disturbance that carries energy from one location to another.
2. A type of signal that has only two possible values.
4. A wave that needs matter around it in order to travel.
6. Describes a material that allows you to see clearly through it.
9. A substance that a wave can travel through or interact with.
10. The use of electronic devices and networks to work with information.
11. A type of electromagnetic wave commonly used to send information wirelessly.
12. Amplitude = Brightness & Frequency = Color For this type of wave, one property affects how bright it appears while another affects its color.
14. A type of wave that does not need matter to travel through.
15. The process of changing information into a signal and later changing it back.
16. A wave in which particles move back and forth along the same direction the wave travels.
20. The distance between matching points on two neighboring waves.
21. Waves produced by vibrations that allow us to hear.
23. What happens when a wave encounters a surface and changes direction by bouncing back.
27. A signal that uses separate, distinct values instead of a continuous change.
29. Describes a material that lets some light through, but makes things on the other side look blurry.
