Asked by Lucy H.

A pipe has one end open and the one end closed. Where must the node be located in order for a standing wave to occur? (The left end, B, is the open one and the right end, A, is the closed one.)
Answered by bobpursley
The antinode is at the open end, the node at the closed end.
Answered by Kyu Q
Are there any times when the node could be in the middle and not at either of the ends?
Answered by bobpursley
yes, but at each harmoic, there will be one node at the closed end, and an antinode at the open.
