Rainbow Facts: Rainbow Facts: A rainbow is an arc of colour in the sky that can be seen 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 created when light is bent (refracted) while entering a droplet of water and reflected. A rainbow is actually round. On the ground, the bottom part is hidden, but in the sky, like from a flying airplane, it can be seen as a circle. Rainbows often appear after storms, and are popular symbols for peace and harmony in many cultures.
Cause: Cause: The rainbow affect can be seen when: There are water drops in the air and the sun is giving light back of the observer at a low distance up or angle. shadow of your head (which is the point opposite the sun). Sunlight is white and is a mixture f many different colours. Water and other materials bend the different colours at different angles, some more strongly than others. This is called dispersion. By splitting up white light into separate colour, rainbows appear colorful even though the light hitting them is white. 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 above. 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 of spectrum in far away rain even if it does not fall on the earth. An unnatural rainbow effect can also be made by spraying drops of water into the air on a sunny day. Rainbows always appear opposite from the sun: they form circles around the
