20 Interesting And Awesome Facts About Rainbows

Rainbows disappear as quickly and as mysteriously as they appear. They are used as symbols for different causes and companies around the globe, and are seen as a symbol of health, happiness and honour. Take a look below for 20 interesting and awesome facts about rainbows.

1. A rainbow is created by the perfect combination of refraction, reflection and then dispersion.

2. There are seven colors perceived in rainbows: Red, Orange, Yellow, Green, Blue, Indigo and Violet, in that order.

3. When water droplets are present in the air, often from rainfall but could also from fog, a waterfall or a fountain, rays of sunlight then reflect off of these and some of the light is then dispersed and reflected back towards the observer.

4. To view a rainbow in the sky, you must be positioned so that the Sun is behind you, and the water droplets in front of you.

5. Rainbows are rare in winter as the crucial water droplets needed for this phenomenon freeze into ice and scatter light in such ways that a rainbow cannot be formed.

6. The colors of the rainbow are formed as light travels more slowly through the water than it does through the air, bending as it does so, thus splitting the light into all of its colors which we normally perceive as white.

7. Rainbows are not actually “bows”, they are in fact full circles but the other half always lies below the horizon and you would have to be looking at it from the sky, like from an airplane if you happened to have one handy, to see the circle.

8. All rainbows are also double rainbows, but the second one is usually too faint to see, it is born with its colors reversed with the red on the inner part of its arc as it has been reflected twice in the water droplets.

14. Sometimes it has more negative connotations: the leprechauns who had stolen gold from the Vikings were said to have hidden their loot at the end of the rainbow, which is an optical effect and thus is impossible to touch let alone approach or deposit gold at the foot of.

15. The first person to take scientific interest in a rainbow is said to be Aristotle, the 4th century BC Greek scholar. His findings were unmatched for many hundreds of years to come and those who took an interest after him would usually revert back to his first findings.

16. More recently, rainbows have taken on contemporary symbolism and represent equality, pride, hope, respect, happiness and peace.

17. In the 1960s people began to use depictions of rainbows at peace marches and anti-nuclear weapon demonstrations.
