In a resonating pipe that is open at one end and closed at the other end, there O A. are displacement antinodes at each end. O B. is a displacement node at the closed end and a displacement antino de at the open end. OC are displacement nodes at each end. O D.is a displacement node at the open end and a displacement antino de at the closed end.
