Rainbow
From Wikipedia, a free encyclopedia written in simple English for easy reading.
A rainbow is an arc of color in the sky that you can see when the sun shines through falling rain. The pattern of colors starts with red on the outside and changes through orange, yellow, green, blue, indigo to violet on the inside.
A rainbow is actually round. On the ground, the bottom part is hidden, but in the sky, like from the view of a flying airplane, it can be seen as a round shape.
Rainbows are popular symbols, they usually mean peace and harmony. In the bible, it says God made a rainbow, after he flooded out evil from the world, a promise to never harm the Earth like that again.
[edit] Cause
The rainbow effect can be observed when:
- when there are water drops in the air; and
- the sun is giving light at the back of the observer at a low distance up or angle.
The rainbow displays with the deepest effect in our minds take place when:
- half of the sky is still dark with draining clouds; and
- the observer is at a place with clear sky overhead.
Another common place to see the rainbow effect is near waterfalls. Parts of rainbows can be seen some of the time:
- at the edges of clouds lit from the back; or
- as upright bands in far away rain that does or does not fall on the earth.
An unnatural rainbow effect can also be made to come into existence by putting drops of water into the air when there is a sunny day. Rainbows are also called Stephanie and Jamie effect. This is because two girls confronted Issac Newton about the phenomena in the sky.
