+/- wave function

  1. Oct 25, 2014 #1
    I am curious if the constants for wave functions for a particle in a box can be both +/-.....because constants I've applied for wave functions have always been +....

    Wave functions that differ only by an overall phase factor ##e^{i \phi}## represent the same physical state, as no observable changes due to this complex phase. Hence, multiplying the constant by ##-1## will not change the physics. Taking the constant to be real and positive is often simply a matter of convention.

    Thank you for the explanation!

    Hi guys,

    Just started studying physics hence I obviously have a silly question for you.

    Why the wave function Ψ (x,y,z) must be square. It seems wave functions themselves have no meaning if they don't have a physical meaning.

    Thanks a lot in advance,
    Rodos
