Why can't you hear a sound when you wave your hand back and forth?

Because you can't wave it fast enough. You'd hear a sound if you could do at least 30 or 40 complete
back-and-forth waves every second, and keep that up for a few seconds.
That's exactly what's going on when you hear the buzz of a fly, or the whine of a mosquito.
They don't wave as hard as your hand does, but they wave a lot faster.
If you wave it close to your ear you can hear the sound.
