Single beats, infinitely many frequencies

  1. May 31, 2013 #1
    Does anyone know how to prove that if we want to make a single wavepacket in space we necessarily have to superpose a continuous infinity of frequencies? Any help much appreciated!

    A wavepacket is an integrable function, and the Fourier transform of an integrable function is continuous.
