Optics you can notice tomorrow
Light and Color
These topics reward attention because they make ordinary skies, mirrors, and reflections feel far stranger and more precise.
Explainers
Pages in Light and Color
Scattering, reflection, mirages, and visual tricks that change what we think we are seeing.
A live sky simulator, a clear explanation of Rayleigh scattering, and a comparison with the Moon and Mars.
Light and Color How do rainbows form?A rainbow lab that lets you move the Sun, change the spray, and darken the storm background to see when an arc strengthens or disappears.
Light and Color Why do stars twinkle?A twinkle lab that lets you change turbulence, altitude, humidity, and apparent size to compare stars with steadier-looking planets.
Light and Color Why do mirages happen?A mirage lab that lets you vary ground heating, viewing distance, air layering, and surface brightness to see when a false pool of water or lifted image appears.
Light and Color Why do mirrors reverse left and right?A mirror-perception lab that lets you vary body rotation, mirror angle, asymmetry cues, and text clues to see when the reflection feels intuitive and when it feels backwards.
Light and Color Why is snow white?A snow optics lab that lets you change grain freshness, packing, meltwater, and soot to see when snow glows bright white and when it turns gray or dingy.
