Prism angle: 60° drag to rotate prism

drag the prism · hover a color ray to inspect wavelength & energy

White light enters as one beam. Inside the glass, each wavelength bends differently. Violet is slower — it refracts more. Red is faster — less. Same material, different behavior. That difference is the spectrum.

Convex lens bends light by refraction. Driver’s Mirror shows the same shape language at side-mirror scale — brain reads small-as-far, slider lies about distance. Parabolic Mirror does the same focal trick by reflection — one dish, one focal point, the building block for Tab III. The shape is the lesson at every scale.

WHAT THIS SHAPE IS FOR

CONVEX — focuses light to a point. Magnifying glass, telescope eyepiece, camera lens, eyeglasses for farsightedness, the survivalist’s fire-starting trick with notebook paper, kids burning ants on the sidewalk. The headline application is the one you just played.

The parabolic mirror focuses via reflection, not refraction. Same geometry — different mechanism. Archimedes used mirrors. The CSP towers use mirrors. Act III shows you why.

Drag mirror handles · converge beams on the hull Syracuse, 214 BC

drag each mirror handle to aim its beam · fill the convergence meter to fire

Archimedes positioned soldiers each holding a polished shield. Each mirror reflects a beam toward a single point on the Roman hull. Individually: warm. Together: ignition. That's the principle.

WHAT YOU'RE LOOKING AT

Every pin is a field of mirrors — heliostats — tracking the sun and reflecting beams to a tower receiver.

Same principle as Act III. Archimedes used shields. These plants use computer-tracked glass. The focal geometry is identical.

Steam from the tower drives a turbine. Some plants store heat in molten salt — generating electricity after sunset.

THE PRINCIPLE CHAIN

Act I — wavelength → photon energy

Act II — lens curves → focal point

Act III — mirrors array → ignition

Act IV — heliostat field → megawatts

Same photon. Redirected at scale.
