Question regarding particles and wavelength

  1. Apr 4, 2009 #1
    1. The problem statement, all variables and given/known data
    I know about particle/wave duality; however, when I read a passage and it says the wavelength of the particle I'm not sure what it's referring to. Is it the actual wavelength of the particle or the wavelength of the wavefunction for a particular eigenvalue?

    2. Relevant equations

    3. The attempt at a solution

    It's the wavelength of a wavefunction corresponding to a particular momentum eigenstate of the particle. So, yes, the latter. See de Broglie.
