Rainbow : All The Best Free Flash Games Relating To Rainbow

A rainbow is a multicolor arch that we can see in the sky from the earth (at a low angle view). It is caused by the refraction and the dispersion of the sun's light by water droplets in the atmosphere.
The natural and optical phenomena that is at the basis of rainbows is quite complex. The white light, when it is dispersed by a prism or a water drop, “splits” into a wide range of colors, visible to the eye.
The rainbows spans a large spectrum of colors. The spectrum is the strip of colors produced when the light gets separated into its multitude of components.

Rainbows are quite impressive to watch. The lower part of it is violet and the upper red. In between, shades of saturated colors like yellow, blue and green are displayed. However some colors, like pink or magenta, are unsaturated colors that cannot be visible to the human eyes. Children, in order to memorize the colors in a rainbow, keep in mind a mnemonic that is: Richard Of York Gave Battle In Vain. The first letter of each word stands for the first letter of the rainbow's colors: Red, orange, yellow, green, blue, indigo and violet.

To get the best of rainbows, it matters a bit where you stand. Actually, the position of the rainbow in the sky depends on the spot from where the observer watches the phenomena. The observer, the sun and the arch's center forms a line, around which the rainbow appears at a 42° angle.
The sun needs to be at an angle lower than 42° or it will “fade” bellow the horizon line. Two people at an extreme point of position may have the impress to see the “roots” of the rainbow, but they're wrong. You'll never see the “end” of a rainbow, even though you feel like you could reach it!
The best “rainbows” are near waterfalls because the mist allows a great dispersion. But when the sun shines very bright just after a rainfall, they may be quite pretty as well!

In the Greek mythology, the rainbow is a path taken by Iris, a messenger, to go back and from heaven to earth. The rainbow was also a path in the animated series “Care Bears”!
