An open organ pipe of length L vibrates in its fundamental mode. The pressure variation is maximumA. at the two endsB. at the middle of the pipeC. at distance L/4 inside the endsD. at distance L/8 inside the ends |

Answer» Correct Answer - B In an open pipe the ends are points of displacement antinodes and hence pressure node. The midpoint (for fundamental mode) is a point of displacement node and hence pressure antinode. ( variation of pressure is maximum at pressure antinode and zero at pressure -node). |
