Why Is The Sky Blue?
10. Rainbows
Rainbows are among the most beautiful natural phenomenon we are likely to see. They can stretch from one end of the sky to the other and will often have vivid colors, clearly showing every color in the spectrum. They can also appear anywhere on the planet when conditions are right, but what are they?

When the sun is out and there is sufficient moisture in the air, such as when it is raining, the light from the sun will travel through the water droplets. This will cause the different wavelengths to separate and refract in the same way they do with a prism. When conditions are ideal, you might even see a double rainbow, which is a larger, fainter rainbow arching over the top of the smaller, brighter one.
