In a resonating pipe that is open at one end and closed at the other end, there is a displacement node at the closed end and a displacement antinode at the open end. This is because at the closed end, the air molecules cannot move and therefore experience zero displacement. At the open end, the air molecules can move freely and therefore experience maximum displacement. This creates a standing wave pattern with a node at the closed end and an antinode at the open end.
