An organ pipe with one end open and the other closed is operating at one of its resonant frequencies.The open and closed ends are respectively:
A)pressure node, pressure node
B)pressure node, displacement node
C)displacement antinode, pressure node
D)displacement node, displacement node
E)pressure antinode, pressure antinode

Question

Quizplus · Accepted Answer

At a resonant frequency of an organ pipe with one end open and the other closed, the open end behaves as a displacement node and the closed end behaves as a pressure node. Therefore, the best choice is B as it states that the open end is a pressure node and the closed end is a displacement node which is incorrect.
