  1. wave
    Rhythmic distrubances that carry energy without carrying matter
  2. mechanical waves
    use matter to transfer energy
  3. transverse wave
    the wave energy causes the matter in the medium to move up and down or back and forth at right angles.
  4. compressional wave
    matter in the medium moves forward and backward along the same direction that the wave travels.
  5. electromagnetic waves
    waves that can travel through where there is no matter.
  6. amplutude
    how waves rises above, or falls bellow the normal level
  7. wavelength
    is the distance from the top of one crest to the top of the next crest, or from the bottom of one trough to the bottom of the next trough.
  8. frequency
    number of wavelengths that pass a given point in 1 sec.
  9. reflection
    wave strikes an object or surface and bounces off.
  10. refraction
    the bending of a wave as it moves from one medium into another
  11. diffraction
    is the vending of waves around a barrier.
  12. interference
    the ability of two waves to combine and farm a new wave when they overlap, the individual waves is
