In an open pipe, the pressure variation at the ends of the pipe is maximum.

A
False
💡 Explanation:
A suction at the end of the tube draws air from further up the tube, and that in turn draws air from further up the tube and so on. So the result is that a pulse of high pressure air travelling down the tube is reflected as a pulse of low pressure air traveling up the tube. So the pressure wave has been reflected at the open end, with a change in phase of 180. In the open-open pipe, there is such a reflection at both ends. So the above argument is false.
