oPhysics: Interactive Physics Simulations

Select a simulation from one of the above categories or click on a category to see descriptions of the simulations for that category.


 Hydrogen Energy Levels

This is a simulation of an atomic energy level diagram of the hydrogen atom.
Charge to Mass Ratio Lab

This is greatly simplified re-creation of J.J. Thomson's experiment, which he used to determine the charge to mass ratio of an electron. The simulation allows you to go through the steps of the experiment and gather data which you can then use to determine the electron's charge to mass ratio.
