Re: Pedagogy of waves, was Total Internal Reflection

 have not been following this thread entirely
 yet the EM wave is a carrier wave, and the
 sound is a signal on that wave, from what
 I understand. the modulation/demodulation
 may have to do with the signal, as the wave
 reproduces its pattern in an antenna at a
 distance. or this is how I though it worked.
