What frequency of sound traveling in air at 11 oC has a wavelength of 4 m?(adsbygoogle = window.adsbygoogle || []).push({});

From what I can come up with... the frequency of sound at 20C is 344 m/s and at -20C is 320 m/s. From this I interpolated and got at 10C it is 332 m/s and then kinda guessing at 11C it is 333.2 m/s.

333.2 / 4 m = 83.3 hz

...thoughts? My main question revolves around my interpolation of the speed of sound in air at 11C
