Consider the wavefunctions, and compare to the probability density: measure the period of oscillation for a given set of well parameters. write down the equation for the wavefunction of an infinite quatum well. given the energy of the state selected, does the period match what is expected? where do the "real" and "imaginary" part of the wavefunction come from. what happens to the wavefunction as the energy approaches the top of the well. explain this observation. why are there only 1-4 states in this quantum well when in the quantum free-electron model there is a quasi-continuum of eneergy states? (ie what is different? )
