If we study the vibration of a pipe open at both ends, then which of the following statements is not true?
Options
(a) Odd harmonies of the fundamental frequency will be generated
(b) All harmonies of the fundamental frequency will be generated
(c) Pressure change will be maximum at both ends
(d) Antinode will be at open end
Correct Answer:
Pressure change will be maximum at both ends
Explanation:
Pressure change will be minimum at both ends. In fact, pressure variation is maximum at l/2 because the displacement node is pressure antinode.
