Key Features

Available Simulations

Drag-and-drop interaction for instant physical intuition. More simulations will be added over time.

🔭

Convex Lens Imaging

Drag the object to instantly see real and virtual image formation. Adjust focal length and simulate half-covered lens experiments.

🔦

Law of Reflection

Move the light source to verify incident and reflection angles live. Arc graphics make angular relationships immediately clear.

🖼️

Virtual Image Construction

Step-by-step animated ray diagram construction. Build geometric intuition for virtual image formation in plane mirrors.

👁️

Field of View & Full Mirror

Dynamically visualize what a mirror reflects. Verify the minimum mirror height for full-body reflection as you adjust position.

Total Internal Reflection

Explore Snell's law and critical angle live. Watch the transition from refraction to total internal reflection as you adjust the beam.

📊

Real-time Data Panel

Live readout of image distance, magnification, and angles. Cross-check optical formulae against simulation results instantly.
