An organ pipe 2.4 m long is open at one end and closed at the other end.

What is the linear distance between a node and the adjacent antinode for the third harmonic in this pipe?


Expert Answer

Step 1


An organ pipe is 2.4 m long and open at one end and closed at other.

Step 2

Showing the diagram of the given case:

The length of the pipe = L 2.4 m As we know, Antinodes and nodes are always formed equidistant. Means, distance between any two adjacent node and antinode pair would be the same. In the given case, the organ pipe has third harmonic, means there are three pairs of Antinode and node So, the distance between an antinode and an adjacent node would be one third of the length of the pipe L So, required distacne = 3 2.4m =0.8m 3 Hence, an adjacent node and antinode are 0.8 m apart
