DeBroglie's hypothesis suggests that every body has particle-like and wave-like properties (which may or may not be observable). This means that I as a person walking down the road with a velocity $v$ would exhibit both particle and wave-like properties (though my wave-like properties would be negligible). My question is: what kind of a wave do I describe? A standing wave or a travelling wave?

  • $\begingroup$ @JohnRennie My question concerns what type of a wave I describe not the problem of computing the deBroglie wavelength for a system of particles. $\endgroup$ – Kunal Pawar Apr 19 '17 at 16:47
  • $\begingroup$ Please note that this doesn't have anything to do with symmetry (either in the QFT sense or in the everyday language sense), saying so is just poetical. Also, you have wave-like properties regardless of whether you move down the road or elsewhere. $\endgroup$ – Helen - down with PCorrectness Apr 19 '17 at 17:42

    $\begingroup$ @KunalPawar as much as I know it would be a probability amplitude wave with negligible wavelength. Standing waves are for the particles that are bound , like an electron in a shell. Had you been trapped in box it would have been a standing wave ( with even lesser wavelength) $\endgroup$ – Shashaank Apr 22 '17 at 9:50

Most likely a wave-packet. But from a QM point of view an incoherent mixture of wave packets (mixed state).
