MyPhysicsLab provides interactive simulations for exploring physics concepts.
Falstad
Falstad hosts interactive applets for exploring math, physics and engineering concepts.
About Falstad
Falstad hosts educational applets that visualize concepts in math, physics, and engineering. Topics include oscillations and waves, acoustics, signal processing, electricity and magnetism, quantum mechanics, linear algebra, thermodynamics, and mechanics.
The applets were originally written in Java and have mostly been converted to Javascript, so they can generally be viewed without a Java-capable browser.
Key features
- Ripple tank simulation showing interference, diffraction, refraction, Doppler effect
- Analog circuit simulator demonstrating various electronic circuits
- Hydrogen atom applet showing orbitals (wave functions)
- 2-D electrostatics applet showing static fields and current distributions
- Gas molecules simulation demonstrating kinetic theory of gases
- Fourier series applet for frequency analysis of periodic functions
Best for: Students and teachers who want to visualize math, physics, and engineering concepts.
Good for
- Includes applets for waves, acoustics, circuits, quantum mechanics, and mechanics
- Most applets work without a Java-capable browser
Watch out for
- Conversion from Java to Javascript is described as mostly complete
