  How do you measure the amplitude of a longitudinal wave?

  check ur notes and textbook.
  
  SGFourms is not the place u stick ur hand out and u get the ans.

  thanks that was helpful. in case u didnt know i have searched on waves on search engines and all that showed was how to calculate amplitude of a transverse wave. if not i ask here for what, you dunno then say dunno la.

  isn't the amplitude of longitudinal and transverse the same? only the direction of travel of particles is not same wat
  
  correct me if i am wrong

  you "change" the longitudinal wave into a transverse wave., where compression is crest and rarefraction is trough, i think.

  Your 'amplitude' of a longitudinal wave is basically the maximum displacement of a particle from its equilibrium position.
  
  In a longitudinal wave, if you measure the displacement of a particle from its equilibrum as a function of time and you plot a graph of its displacement versus time, you will get a transverse graph of displacement vs time.
  
  Hence the amplitude is thus the maximum displacement of a particle in a longitudinal wave from its equilibrium position.
  
  A bit hard to visualise, but these are the principles.
  
  Cheers!

  You are welcome.
  
  I am merely just going through what I need to know for my upcoming prelims
