View Full Version : 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.
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.
