Hi,
I was studying the solution of Schrodinger equation with no potential and found that the wave function is just a single plane wave eikx for movement of the particle in positive x direction.
But when the phase velocity of a single wave is calculated it turns out to be less than the particle's velocity and from that argument is made that the de broglie wave, which is associated with a particle, is not a single wave but superposition of waves.
So my question is that how one single wave (which we have found by solving TISE for no potential) can describe a particle, when from the calculation of phase velocity and group velocity we know that a particle can be described by a group of waves?
Any kind of help will be highly appreciated.Thanks in advance
