A two end open pipe organ's 5th harmonic produces a frequency of 260 Hz. If it is 23 degrees Celsius, what is the length of the tube? (2 answers)
Fn=n(v/2L)
Fn=260 Hz
n=5
v=332+0.6(23)=345.8 m/s
I got 3.325 meters as the length, but it says there's two answers. Why is there two answers and what's the other answer?

Is it possible that the length of the tube is 1/2 wavelength, and one wavelength?
I don't understand why the length would be 1/2 the wavelength and one wavelength. I thought that was only for the fourth and second harmonics.
