SUMMARY
Closed pipes cannot produce even-numbered harmonics due to their physical structure, which requires a pressure node at the closed end and a pressure antinode at the open end. This configuration allows only odd harmonics, with the first overtone being three times the fundamental frequency. The absence of even harmonics is confirmed by the relationship that even harmonics cannot satisfy the condition of having a closed end at an even integer multiple of the wavelength. Understanding this principle is crucial for A-level physics students.
