Spectrum

All light is the same thing at different sizes. Radio waves longer than the Earth, the colours you see, gamma rays smaller than a nucleus: thirty powers of ten of one spectrum, end to end.

    This is an alpha: some things are unfinished and will change. Data from the CIE, NIST, ASTM, NASA and others: see sources. Sister site: Molecule Viewer. ·
