SPECTRAL ANALYSIS — LIGHT DIFFRACTION RAINBOW

VISUAL STYLE: Light diffraction and spectral analysis made visible — the moment when white light is separated into its component wavelengths by a prism, diffraction grating, or spectrograph. Pure physics producing pure beauty. The rainbow as science rather than weather.

COLOUR PALETTE: The full visible spectrum in correct wavelength order, rendered at maximum saturation — deep violet (380nm) through indigo, electric blue, vivid cyan, pure green, acid yellow-green, warm yellow, orange, to deep red (700nm). This is not an approximation of the spectrum — it is the spectrum. Each colour occupies exactly the bandwidth it would in physical diffraction. Beyond the visible: implied ultraviolet at the violet end, implied infrared at the red end — the spectrum extending beyond what the eye can see.

DIFFRACTION EVENTS: The central visual drama — white light entering a prism or striking a diffraction grating, the beam separating into its component colours in a fan of pure spectral light. The separation is clean and precise — each wavelength bending by exactly the right amount.

SPECTRAL LINES: Where specific elements are present, their emission or absorption lines appear — bright lines at specific wavelengths for emission spectra, dark lines against the rainbow for absorption. The fingerprint of hydrogen, helium, sodium — the way astronomers identify the composition of distant stars.

INTERFERENCE: Where diffracted light overlaps, interference patterns appear — bright and dark bands at precise intervals, Newton's rings, thin film colours. Physics made visible.

MOTION: Light always moves. Diffraction happens at the speed of light. But the patterns it creates — the spreading rainbow, the interference fringes — can be made to evolve slowly, as if the physics is running in slow motion for observation.

No photographs. No physical prisms or equipment. No real people. Pure spectral colour, pure diffraction physics, pure wavelength throughout.
