1. The problem statement, all variables and given/known data The sound emitted by bats has a wavelength of 3.5mm. What is the sound's frequency in air? Assume that the bat is flying through air with a temperature of 30 degrees C. 2. Relevant equations V=331.4 + 0.6*Temp.C V=wavelength*frequency 3. The attempt at a solution V= 331.4 + 0.6(30) V=349.4m/s V=wavelength*frequency 349.7m/s=0.0035*f f=99829.6hz The only thing I'm not sure about is did I need to change the 3.5mm to .0035m?
