In a resonating pipe that is open at one end and closed at the other, 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 are unable to vibrate and hence, there is zero displacement. At the open end, the air molecules can vibrate freely and hence, there is maximum displacement.
