Quick conceptual help!

    Ok, I don't understand why in a sound resonating pipe, that the in the closed end there needs to be a node and not antinode. Why?

    IIRC, you want to look at the reflected wave.

    huh? Can you elaborate?

    Sorry, my mistake, I was thinking of a transverse wave, not a longitudinal wave.


    Recall that nodes are where the particles do not oscilate about their rest position... does that help?

    Right. I get that. But what would it make a difference if i had a anti-node instead on a closed pipe?

    Well, it's kind of difficult for air particles to oscillate through the pipe...

    wait. Ok imagine the pipe, it has a plunger and an open side on the opposite end. Why would air particles have trouble? It is coming from the open side or the anti-node side.

    When I said through, I meant through the closed end.
