A stationary sound wave is established in a resonant air column inside a pipe closed at one end.
Which statement about this stationary wave is not correct?
Air molecules at adjacent displacement antinodes vibrate in phase with each other.
The closed end of the pipe is a position of zero displacement variation but maximum pressure variation.
All air molecules between two adjacent displacement nodes oscillate in phase.
The wave pattern stores energy but does not propagate energy along the axis of the pipe.
