   The iris; the semicircle of various colours which appears in showery weather.

   Etymology: rain and bow.

   Casting of the water in a most cunning manner, makes a perfect rainbow, not more pleasant to the eye than to the mind, so sensibly to see the proof of the heavenly iris. Philip Sidney.

   To add another hue unto the rainbow. William Shakespeare.

   The rainbow is drawn like a nymph with large wings dispread in the form of a semicircle, the feathers of sundry colours. Henry Peacham.

   They could not be ignorant of the promise of God never to drown the world, and the rainbow before their eyes to put them in mind of it. Thomas Browne, Vulgar Errours.

   This rainbow never appears but where it rains in the sunshine, and may be made artificially by spouting up water, which may break aloft, and scatter into drops, and fall down like rain; for the sun, shining upon these drops, certainly causes the bow to appear to a spectator standing in a true position to the rain and sun: this bow is made by refraction of the sun’s light in drops of falling rain. Isaac Newton, Opticks.

   The dome’s high arch reflects the mingled blaze,
   And forms a rainbow of alternate rays. Alexander Pope.

1. Rainbow

   A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun. Rainbows can be full circles. However, the observer normally sees only an arc formed by illuminated droplets above the ground, and centered on a line from the sun to the observer's eye. 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 when 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, with red on the inner side of the arc. This is caused by the light being reflected twice on the inside of the droplet before leaving it.

1. 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. 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.

Examples of Rainbow in a Sentence

1. Hampton Jr.:

   We attempt Best Supporting Actor to not walk in the footsteps but in their Black Panther Party paw steps, and not just in theory, not in a romanticized type of way( but) with our programs, with our criticisms, with our self-criticisms, with our struggles, our politics of internationalism, with the present-day Rainbow Coalition, with the Triple Cs -- the children, community and Black Panther Party Cubs -- supplying services for the people, not in a charity type of way but where people themselves can get involved and fight for their own self-determination.

If they're OK with who they are, the world should be, too.
