A bat emits a sound whose frequency is 83.2 kHz. The speed of sound in air at 20.0 oC is 343 m/s. However, the air temperature is 40.5 oC, so the speed of sound is not 343 m/s. Assume that air behaves like an ideal gas, and find the wavelength of the sound.

    L = V/F = 343m/s / 83200cy/s = 0.004 m.
