Regarding open organ pipe, which of following is correct?
Regarding open organ pipe, which of following is correct?
- A. Both ends are pressure antinodes
- B. Both ends are displacement nodes
- C. Both ends are pressure nodes
- D. Both (1)and (2)
Step-by-step solution
In an open organ pipe, both ends are open to the atmosphere, so the pressure is fixed at atmospheric pressure, making them pressure nodes (pressure is minimum). Displacement is maximum at the ends, so they are displacement antinodes. Therefore, only option C is correct.
