What is a closed pipe ( standing waves)

  1. Nov 27, 2014 #1
    1. The problem statement, all variables and given/known data
    does it mean only one side of the pipe is open or both sides are closed.

    2. Relevant equations

    3. The attempt at a solution
    i think it means only one side is open, but i just need to make sure

    Perhaps you should give the phrase to us in context so we can assess.

    You will see nodes forming at the closed side of the pipe.
    It prevents the air from vibrating at that end.
    The waves are reflected with an inversion and thus
    interferes destructively forming the node.
    At an open end the waves are reflected without inversion
    causing constructive interference and forming a large
    amplitude vibration at this end of the pipe.

    This educational film is old, but very informative...

    We don't know if anything is being blown into the pipe. Sound could be transmitted through a diaphragm at one end.
    As DaveC426913 writes, we need the whole context.
