Answer:
There is a displacement node at the closed end and a displacement antinode at the open end.
Step-by-step explanation:
This is because at the closed end of the resonating pipe, there is minimum displacement of the wave, and when there is minimum displacement, we have a displacement node. At the open end, we have the maximum displacement of the wave and the point of maximum displacement of a standing wave is its antinode. So, there is a displacement antinode at the open end of the resonating pipe.
