In music, middle C has a frequency of about 256 Hz - the precisefrequency depends on the tuning scheme. How does the wavelength ofa middle C note propagating through air compare to the size of atypical human body? How does the wavelength of the same notepropagating through water compare to the human body? What frequencyof sound in air has a wavelength nearly the size of a human head?This size is important because we have diminished ability todetermine the direction to a source of this tone.
