explanation for children ... The technical details of rainbow formation were first analyzed by Isaac Newton in 1665. His brilliant optics work concerning reflection and refraction certainly does not detract from the beauty and promise of the rainbow.

We will discuss the formation of a rainbow by raindrops. It is a problem in optics that was first clearly discussed by Rene Descartes in 1637. An interesting historical account of this is to be found in Carl Boyer's book, The Rainbow From Myth to Mathematics.

A rainbow occurs when rain is falling in one portion of the sky and the sun is shining in another. For a rainbow to be seen, the sun must be behind an observer who is facing falling rain.

People have been asking questions about rainbows since the beginning of time. One question frequently asked is, how far away is that rainbow? That is a tough one. How far away are the raindrops that produce it? It is hard to judge how far away a rain cloud is;

We show that for strong enough fields, a sharp peak in the rotor angular distribution can be achieved via a time-domain focusing phenomenon, followed by the formation of rainbowlike angular structures. A strategy leading to the enhanced angular squeezing is proposed that uses a specially designed sequence of pulses.

The Formation of the Rainbow ... Rainbows are not limited to the dispersion of light by raindrops. The splashing of water at the base of a waterfall caused a mist of water in the air which often results in the formation of rainbows. A backyard water sprinkler is another common source of a rainbow.

The rainbow ... The sun light enters from the left and always travels in a horizontal line in this applet. The y coordinate of the incident light can be changed by clicking in the area of the upper half of the drop of water and doing a drag. ... Therefore, the rainbow can be best seen in this direction.
