1. A disturbance that travels energy from place to place
Wave
2. The ability to do work or cause change
Energy
3. A repeated motion
Vibration
4. Material or matter through whcih the wave travels
Medium
5. Waves that do need a medium.
MechanicalÂ Waves
6. Waves that do not need a medium. Can travel through a vacuum.
Electromagnetic Waves
7. Waves moves the medium at right angles to the direction in whcih the waves travel.
Transverse
8. Highest point in a transverse wave
Crest
9. Lowest point in a transverse wave
Trough
10. Move the medium parallel to the direction in which the waves travel
Longitudianl Waves
11. Where the particles of the medium are close together
Compression
12. Where the particles are spread apart
Rarefaction
13. The greatest movement of the medium from the rest position
Amplitude
14. The normal position or the field, when it is not being disturbed
Rest position
15. The distance between two corresponding point of a wave.
Wavelength
16. The number of complete waves that pass a given point in a certain amount of time.
Frequency
17. The buncing back of a wave off a suface through which it cannot pass.
Reflection
18. The angle of incidence equals the angle of reflection
Law of Reflection
19. The bending of waves due to change of speed.
Refraction
20. The bending and spreading out of a wave when it moves around a barrier
Diffraction
21. The interaction between waves that meet
Interference
22. Occurs when waves meet to make a larger amplitude
Contstructive
23. Occurs when maves meet to make a smaller amplitude
Destructive
24. An incoming wave and a reflected wave that have just the right frequency, can produce a combined wave. Appears to be stabding still.
Standing Waves
25. An increase in a vibrations amplitude.Caused by external vibrations matching an objects natural frequency.
Resonance
26. Faster than other waves
Primary waves
27. Transverse and logitudinal waves cannot travel through liquids, so they do not go through the liquid core.
Secondary Waves
28. Combination of transverse and longitudinal waves, travel allong the surface of the Earth
Surface Waves
29. Huge ocean wave caused by an earthquake in the crust beneath the ocean floor.
Tsunami
30. An instrument that detects and records earthquake waves.
