    in eqn 5.13 small psi is wave fxn which satisfies time independent SR eqn while Capital psi which is time evolution of small psi is called wave fxn

    wave function does not satisfy Schrödinger eqn??

    eduncle-logo-app

    ..it satisfies time dependent SR eqn

    what is the physical significance of eigen function

    eduncle-logo-app

    eigen fxn has the same significance as wave fxn. difference is that wf has time evolution.

    eduncle-logo-app

    means we can assign every details about the particle as we want.

    eduncle-logo-app

    we can get every information of particles from eigen function

    ??

    eduncle-logo-app

    yes......like operate momentum operator get momentum eigen value, and so on. However wf itself has no physical significance but with its help we can get information about particles.

    Wave function means total wave fxn containing time part too. While eigen fxn have eigen value which is energy.
