Homework Help: Stationary waves in a tube

  1. May 21, 2007 #1
    1. The problem statement, all variables and given/known data
    For a tube with one end open and one closed
    a) Draw a labelled sketch of the stationary wave patter for (i) the fundamental and (ii) the next highest mode.

    b)describe the physical quantity graphed (as the verticle axis, i.e. the dependent variable)

    c) clearly explain the reason for the behaviour of this quantity at (i) the closed and (ii) the open end

    3. The attempt at a solution
    For a) would I draw a sketch of the displacement of the pressure?
    part b) just seems like one of those weird questions that has nothing to do with part a:confused: . Can somebody help me to decypher it?

    My guess is the question wants you to graph some physical quantity on the y-axis and length on the x-axis. So 'sketch' must mean 'graph' ?

    Or they've provided a graph and you've missed it ?

    no graphs anywhere :confused:

    What do you recommend I draw for a)?
