参考答案: Listening
to music while seated far away from the source of sound gives evidence that the
speed of sound in air does not depend on frequency. If the speed were highly frequency dependent,
then high and low sounds created at the same time at the source would arrive at
your location at different times, and the music would sound very
disjointed. The fact that the music
“stays together” is evidence that the speed is independent of frequency.
