These are the some of the more popular and fun applets in Physics 2000, including previews of some that are not yet integrated contextually into the site.Bose-Einstein CondensationEvaporative CoolingSee how evaporative cooling works, both in your coffee cup and in Bose-Einstein Condensation.
Laser CoolingAnother piece from the Bose-Einstein Condensation pages. See how lasers can be used to "cool" matter by slowing down atoms. In three parts.
Optical MolassesA demonstration of how multiple laser beams can be used to actually cool and confine atoms.
Microwave OvensWater in a MicrowaveThis applet demonstrates how a microwave field makes a water molecule oscillate back and forth, leading to heating in food.Cooking "Nodes" in a Microwave OvenTry "nuking" some marshmallows in a microwave oven and see how they cook at different rates in different parts of the oven.
Dipole Molecule in a Changing FieldSee conceptually how the electromagnetic field of one charge will move a dipole molecule (water) around like a compass needle.
The Two-Slit ExperimentYoung's Two Slit ExperimentPlay with the classic "two slit" experiment using lasers to show interference patterns.Feynman's Two Slit ExperimentIn this one, shoot a stream of electrons through the two slits and see how the interference patterns still appear. How bizarre, how bizarre.
Wave InterferenceStretch and shift two waves and see how they add together to interfere both constructively and destructively.
X-rays and CAT ScansFluoroscopeAmaze your friends! A fun demonstration of what it looks like to "see" in the x-ray portion of the spectrum.
X-Ray EmissionsSee how tungsten atoms are used to produce x-rays using both "Bremsstrahlung" and "K-Shell Knockout".
Schrödinger & Bohr Atomic ModelsA side-by-side comparison of the Schrödinger and Bohr models of the hydrogen atom and how it absorbs and emits photons.
Electromagnetic Waves and ParticlesOrbitsPlace negatively charged particles around a positively charged nucleus and see how the particles "fall" into stable orbits. Also demonstrates gravitational orbits.
Fieldwaves"Particle on a Spring" shows how an oscillating charge propagates a wave through a single "line" of a field.
Force FieldPut down "test charges" in an electromagnetic field to see how the pattern of the field appears.
Interactive Force FieldIn this version you can add, modify, and drag the charges that create the field to see how the test charges are affected.
