SUMMARY
An organ pipe open at both ends resonates at its first resonant length with a frequency of 128 Hz. Given the speed of sound at 346 m/s, the wavelength can be calculated using the universal wave equation. The length of the pipe corresponds to half the wavelength, as an open pipe contains two wavelengths for its fundamental frequency. Therefore, the length of the pipe is 1.35 meters.
