Displacement envelope of standing wave in pipe of length L.
Displacement envelope of standing wave in pipe of length L.
A standing sound wave is established in an air-filled pipe of length \(L\) that is closed at \(x = 0\) and open at \(x = L\). The graph shows the displacement envelope of the air molecules as a function of position \(x\) along the pipe. Which of the following statements correctly identifies and explains the locations of maximum pressure variation in the pipe?
