A one metre long (both ends open) organ pipe is kept in a gas that has double the density of air at STP. Assuming the speed of sound in air at STP is $\displaystyle 300 \mathrm{~m} / \mathrm{s}$, the frequency difference between the fundamental and second harmonic of this pipe is \_\_\_\_ Hz.
Official answer
106.6 ± 0.6
