48. If we study the vibration of a pipe open at both ends, then which of the following statements is not true?
[2013]
(a) Odd harmonics of the fundamental frequency will be generated
(b) All harmonics of the fundamental frequency will be generated
(c) Pressure change will be maximum at both ends
(d) Antinode will be at open end
Show Answer
Answer:
Correct Answer: 48. (c)
Solution:
- (c) Pressure change will be minimum at both ends. In fact, pressure variation is maximum at $\ell / 2$ because the displacement node is pressure antinode.
