In a closed organ pipe, the harmonics produced are based on odd integers. The fundamental frequency is the first harmonic, and the overtones follow a specific pattern. For a closed pipe, the Pth overtone corresponds to the formula:

Understanding the Harmonics

The harmonics in a closed organ pipe are given by:

  • 1st harmonic (fundamental): 1
  • 2nd harmonic (1st overtone): 3
  • 3rd harmonic (2nd overtone): 5
  • 4th harmonic (3rd overtone): 7

Finding the Pth Overtone

From this pattern, we can see that the Pth overtone is represented by the formula:

2P - 1

Correct Answer

Therefore, the correct option for the Pth overtone in a closed organ pipe is:

B. 2P - 1
