Interesting Facts About RAINBOW

A rainbow is an optical phenomenon that causes a spectrum of light to appear in the sky when the Sun shines on to droplets of moisture in the Earth's atmosphere. It takes the form of a multicoloured arc. Here are some interesting facts about this amazing Phenomena :-

1. It was SIR ISAAC NEWTON who discovered that sunlight falling upon a prism could split into its component colours. This process is known as DISPERSION.

2. When view from the ground, a rainbow appears as all or part of a great arc of colour. When viewed from a plane it is possible to see an entire circle as you can look down on raindrops as well as up to them.

3. You dont necessarily need to have rain to have a rainbow. Rainbows can be formed by the mist of water droplets created by a waterfall. There is even a man who makes rainbows using water sprays on fire-fighting boats.

4. Rainbows are the universal symbol of peace and harmony. IRIS was the Greek goddess of the Rainbow.

5. Rainbows can also be seen during night time !! Moonlight can produce enough light to create a rainbow at night. This is a 'moonbow'. Moonbows are rare because moonlight is not very bright.

6. An old European belief is that anyone passing underneath a rainbow would be changed from a man into a woman or woman into man

7. You often see a rainbow after rain. The sun is always behind you and the rain in front of you when a rainbow appears, so the center of the rainbow's arc is directly opposite the sun.

8. Most people think the only colors of a rainbow are red, orange, yellow, green, blue, indigo, and violet, but a rainbow is actually made up of an entire continuum of colors—even colors the eye can't see!

9. The seven colors of the rainbow correspond to the seven energy centers of the body. Rainbows are positive energy, they have relaxing and healing qualities

10. You can never actually reach the end of a rainbow. As you move, the rainbow that your eyes see moves as well, because the raindrops are at different spots in the atmosphere, so it will always "move away" at the same rate that you are moving.
