About Rainbows

Primary Rainbow and faint secondary rainbow in the background.

We are aware that there is not pot of gold at the end of the rainbow, in fact if you see a person at the end of the rainbow, he wouldn’t be able to see it.

Newton showed that a prism could break up white light into a range of colors; He used the seven color names red, orange, yellow, green, blue, indigo, and violet for segments of the spectrum (analogy with the seven notes of the musical scale).

Other facts:

–       A rainbow is observed in the direction opposite to the sun

–       Occasionally, a secondary bow may be observed, which is considerably less intense than the primary bow and has its color sequence reversed.

–       Rainbows can be caused by many forms of airborne water. These include not only rain, but also mist, spray, and airborne dew.

–       The rainbow is composed of Newtons 7 primary colors red, orange, yellow, green, blue, indigo (like a dark blue) , and violet.
