Frequently asked questions
Technical and pedagogical details
Each simulation implements standard differential equations: Newtonian mechanics (Euler or Runge-Kutta integration), Kirchhoff's laws for circuits, and wave optics approximations. Results are validated against analytical solutions.
The virtual lab runs in any modern web browser with JavaScript enabled. No plugins or installations required. Recommended: desktop or tablet with at least 8GB RAM for complex optics simulations.
Yes. Each lab includes learning objectives, procedural steps, and data export features. Many instructors assign these as pre-lab exercises or for remote learning scenarios.
Measurement precision depends on the simulation: pendulum period errors < 0.5%, circuit voltages ±1%, and optical diffraction patterns match theoretical intensities within 2%.
No. All experiments are completely free and do not require any user account. Source code is available for educational institutions upon request.
