The program, which you may download, in its first part shows wave packets of up to ten sinusoïdel waves, and compares the phase and group velocities in dispersive and non dispersive media.
In its second and third parts, it shows the wave functions of a particle in quantum mechanics (obeying the Schrödinger equation ) with a potential composed of thtree zones having constant but différent potentials.
In its second parts, it shows behaviours of sinusoïdal waves when reaching steps of potential. These steps may be higher than the energy of the wave, with the particular case of the tunnel effect
Finally, in its third part, are shown the energies and wave functions of the eigenstates for systèms where the potential of the central part is less than those of the two others( » potential well »).
