Electrons

When do photons, electrons, and atoms behave like particles and when do they behave like waves? Watch waves spread out and interfere as they pass through a double slit, then get detected on a screen as tiny dots. Use quantum detectors to explore how measurements change the waves and the patterns...

Build an atom out of protons, neutrons, and electrons, and learn about its mass, charge, structure, and nomenclature. * Describe the structure of an atom * Connect protons to element identity * Connect neutrons to nucleus stability * Connect electrons to ionic charge * Describe the mass and...

See how light knocks electrons off a metal target, and recreate the experiment that spawned the field of quantum mechanics.


Platforms: Mac

Simulate the original experiment that proved that electrons can behave as waves. Watch electrons diffract off a crystal of atoms, interfering with themselves to create peaks and troughs of probability.

A capacitor is a device for storing charge. In this simulation, you can investigate a relatively simple capacitor, known as a parallel-plate capacitor. It consists of two identical metal plates, placed parallel to one another. The capacitor can be charged by connecting one plate to the positive...
