  • vibration - a repeated motion and produced by back and forth or up and down movement of an object.
  • Wave - a traveling disturbance that carries energy from one place to another with or without a medium.
  • Medium - a substance that carries the wave.
  • what are the two types of waves?
    mechanical and electromagnetic
  • Wave - according to presence of absence of a medium
  • mechanical wave - it requires a medium to propagate
  • electromagnetic wave - it does not require a wave to propagate
  • Three types of wave?
    transverse, longitudinal and surface wave
  • transverse wave - a wave in which particles of the medium move in a direction perpendicular to the direction where the wave moves.
  • longitudinal wave - a wave in which particles of the medium move in a direction parallel to the direction where the wave moves
  • surface wave - a wave in which particle of the motion medium undergo a circular motion
  • frequency - is the number of waves passing through a given point in one second
  • period - is the time taken to generate one complete wave
