The Free Gaussian Wave Packet model simulates the time evolution of a free-particle Gaussian wave packet in position and k (momentum) space. The position-space and k-space (momentum-space) wave functions are depicted using three colors on the graph to depict the absolute square of the wave function, the real part of the wave function, and the imaginary part of the wave function. The user may change the wave packet's initial width, its initial average position, and its initial average k value (momentum).
The Free Gaussian Wave Packet model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_qm_free_gaussian.jar file will run the program if Java is installed.

The EJS Photoelectric Effect model simulates the Photoelectric effect discovered by Hertz in 1887 and described theoretically by Einstein in 1905. Light of a given frequency (and energy) shines on a metal. If the frequency (energy) of the light is greater than the work function, W, of the metal, electrons are ejected and can form a current (which is shown in milliAmperes). These photoelectrons will also have a kinetic energy if the energy of the light is greater than the workfunction. they will have kinetic energy. If subjected to an electric potential the electrons can be stopped from reaching the plate and stop current from flowing in a circuit.
