Organ Pipes & Resonance Tube
If we study the vibration of a pipe open at both ends. then the following statement is not true.
Show answer and solution
Answer: (b)
- (a) True: an open pipe gives all harmonics. (d) True: odd harmonics are among them.
- (c) True: open ends are displacement antinodes.
- (b) False: at open ends pressure stays atmospheric, so pressure change is zero (pressure node).
- So the answer is (b).
