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.
In a "primary rainbow", the arc shows red on the outer part and violet on the inner side. This rainbow is caused by light being refracted while entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it.
In a double rainbow, a second arc is seen outside the primary arc, and has the order of its colours reversed, red facing toward the other one, in both rainbows. This second rainbow is caused by light reflecting twice inside water droplets.

Famous quotes containing the word rainbow:
“The Rainbow comes and goes,
And lovely is the Rose,”
—William Wordsworth (17701850)
“Captain, the man of skill, the expert
Leader, the creator of bursting color
And rainbow sortilege, the savage weapon
Against enemies, against the prester,
Presto, whose whispers prickle the spirit.”
—Wallace Stevens (18791955)
“Once it chanced that I stood in the very abutment of a rainbows 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 (18171862)
