- - - - example: ripples of water
  - - - vibration of medium
        
        parallel - direction of waves
    - - seismic waves
        
        travel across surface
    - - vibrates at right angles
        
        direction of wave
  - - - distance between point
        
        and same point after new cycle
    - - Wavelength * Frequency
    - - number of complete cycles
        
        in a given time
    - - maximum displacement
        
        of medium - rest position
- - - - changing electrical fields & magnetic fields
  - - - example: can travel through light
