Rainbow – A True Natural Beuty

A rainbow is an optical and 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 arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.

A rainbow is not located at a specific distance from the observer, but comes from an optical illusion caused by any water droplets viewed from a certain angle relative to a light source. Thus, a rainbow is not an object and cannot be physically approached. Indeed, it is impossible for an observer to see a rainbow from water droplets at any angle other than the customary one of 42 degrees from the direction opposite the light source. Even if an observer sees another observer who seems “under” or “at the end of” a rainbow, the second observer will see a different rainbow—farther off—at the same angle as seen by the first observer.

“Be thou the rainbow in the storms of life. The evening beam that smiles the clouds away, and tints tomorrow with prophetic ray.”
Lord Byron

“I’ve always taken ‘The Wizard of Oz’ very seriously, you know. I believe in the idea of the rainbow. And I’ve spent my entire life trying to get over it.”
Judy Garland
