A certain pipe produces a fundamental frequency f in air.(adsbygoogle = window.adsbygoogle || []).push({});

If the pipe is filled with helium at the same temperature, what fundamental frequency does it produce? (Take the molar mass of air to be M_air, and the molar mass of helium to be M_He). The ratio γ of heat capacities for air (7/5) and for Helium (5/3).

I'm not sure how to approach this question.

Any help would be great.

Thanks.
