  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.
    Mechanical 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.
    Siesmograph
