Question
The amplitude of a standing sound wave in a long pipe closed at the left end is sketched in the diagram. The vertical axis is the maximum displacement of the air, and the horizontal axis is along the length of the pipe. What is the harmonic number for the mode of oscillation illustrated?

What is the harmonic number for the mode of oscillation illustrated?Explanation / Answer
At the closed end of the open tube we observe a node and the tube contains only one node and one anti node. Thus, the wave inside the tube must be first harmonic
