How does a wave pass thru a medium?

  1. Jul 11, 2011 #1
    i mean i know particles move up and down but i want to go into a bit more detail.consider a constant fequency wave passing thru a rope.now what i wanna know is that when the wave passes do all the particles bcome crest and trough turn by turn or do some specific particles (those which bcame crest and trough on the first wavelength) bcome crests and trough again and again after each wavelength?
    kindly xplain

    Each particle reached by the wave oscillates up and down (for a transverse wave on a rope), between two extreme positions.
