Davisson-Germer Experiment is a physics simulation tool. It is a simulation model that is intended to show what the Davisson-Germer experiment was about. Basically, the experiment confirmed the de Broglie hypothesis, which says that particles of matter (in the case of this simulation, electrons) have wave properties, or, they act like waves.
The simulation consists of a gun that "shoots" electrons towards a wall of atoms that interfere with the electrons. You will see when you start the gun that the electrons reflect off of those atoms due to wave interference. You can shoot the gun continuously or in short bursts. There is a velocity sliding bar at the bottom of the screen that you can use to increase the velocity of the electrons, and see what effect an increased speed has on the stream of electrons when they collide with the atoms.
Just like all the other PhET simulations available at the University of Colorado, Department of Physics' websites, this one was written in Java, which makes it available in a variety of different platforms. There are a few learning guides on the website that you can download to help you better understand the application.
Simulate the original experiment that proved that electrons can behave as waves.
