The Light Museum
From candles to lasers — how light bends, bounces, and reveals the invisible. Build optical paths, trace rays, and explore 12,000 years of illumination.
Ray Tracer
Place lenses, mirrors, and prisms. Snell's law (n₁ sinθ₁ = n₂ sinθ₂) bends every ray at each interface; the lensmaker's equation handles curved surfaces; total internal reflection kicks in past the critical angle.
The Collection
36 artifacts spanning 12,000 years — from oil lamps to the James Webb Space Telescope. Click any card to copy its description.

12,000 Years of Light
Key milestones from 10,000 BC to 2022 — from the first oil lamps to JWST's mid-infrared instruments.
Hands-on Instruments
Refract light through eight common media with Snell's law, explore the full electromagnetic spectrum, and watch intensity fall as 1/r² from any source.
