An open pipe of length vibrates in the fundamental mode. The pressure variation is minimum
Options:
Answer:
A
Solution:
In an open pipe, the open ends always act as displacement antinodes because the air particles are free to move.
A displacement antinode corresponds to a pressure node, which is a point where the pressure variation is minimum (zero).
In the fundamental mode of vibration, displacement antinodes are formed at the two open ends and a displacement node is formed at the middle of the pipe.
Therefore, the pressure variation is minimum at the two ends.
Answer: At the two ends.
