Waves

3. a measure of how fast a wave is moving.
9. the reflection of a sound wave from a surface back to the listener.
13. this occurs when one wave comes into contact with another wave.
14. the distance between two successive crests of a wave.
15. Wave, a wave that contains an electric and a magnetic field and can travel through a vacuum.
17. the highest point of a wave.
18. interference, when two waves arrive at the same point in phase and the disturbances add together.
19. a special type of electromagnetic wave that has a frequency which we can see.
21. wave, a wave where the disturbance is parallel to the direction of propagation.
25. wave, a wave that much travel through some sort of matter.
26. electromagnetic radiation waves with the longest wavelength.
28. this occurs when a wave bends around an object.
30. wave, a wave where the disturbance is parallel to the direction of propagation.
31. position, the position of a medium would take if there were no wave.
32. area of a wave with the maximum density.

1. a mechanical wave caused by a vibration and which we can hear.
2. electromagnetic radiation waves with the shortest wavelength.
4. wave, a wave where the disturbance is perpendicular to the direction of propagation
5. interference, when two waves arrive at the same point out of phase and the disturbances detract from each other.
6. the lowest point of a wave.
7. this occurs when a wave moves from one medium to another changing direction and wavelength.
8. the tendency of a system to oscillate with greater amplitude at certain frequencies.
10. a measurement of the strength of a sound wave.
11. the time between the crests of a wave.
12. this occurs when a wave bounces off a boundary and changes direction.
16. a unit used to measure the intensity of a sound
20. the maximum displacement of a wave from it's resting position. Higher this equals higher the energy.
22. the matter through which waves travel through.
23. the taking in or energy by a medium
24. a traveling disturbance that transfers energy, but not matter, from one place to another.
26. area of a wave with the minimum density.
27. wave, a wave where the disturbance is perpendicular to the direction of propagation
29. the number of times per second that a wave cycles
