Rainbow

A rainbow is an optical and meteorological phenomenon that is caused by reflection of light in water droplets in the Earth's atmosphere, resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured arc.
Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.

Famous quotes containing the word rainbow:

    One doesn’t look at a rainbow any longer that lasts a quarter of an hour.
    Johann Wolfgang Von Goethe (1749–1832)

    Once it chanced that I stood in the very abutment of a rainbow’s arch, which filled the lower stratum of the atmosphere, tinging the grass and leaves around, and dazzling me as if I looked through colored crystal. It was a lake of rainbow light, in which, for a short while, I lived like a dolphin. If it had lasted longer it might have tinged my employments and my life.
    Henry David Thoreau (1817–1862)

    She saw in the rainbow the earth’s new architecture, the old, brittle corruption of houses and factories swept away, the world built up in a living fabric of Truth, fitting to the over-arching heaven.
    —D.H. (David Herbert)
