Hey guys, need some help here with a problem. I've gotten half way thru and don't know where to go next. Here's the problem:(adsbygoogle = window.adsbygoogle || []).push({});

The wavelength of a 40,000-Hz ultrasound wave is measured to be 0.868cm. Find the air temperature.

Using v = frequency(wavelength)

40,000-Hz(0.868cm) = v

v = 347 m/s

I'm not sure where to go from here? ...Thanks for any advice!
