Introduction
1) Light may look colorless but it is really made up of many different colors.
2) Those colors consist of red, orange, yellow, green, blue, indigo and violet.
3) These colors are known as the spectrum.
4) A rainbow is a meteorological phenomenon that is caused by reflection.
5) It takes the form of a multicolored arc.
6) Rainbows caused by sunlight always appear in the section of sky opposite of the sun.
7) In a rainbow, raindrops in the air act as tiny prisms.
8) Light enters the raindrop, reflects off of the side of the drop and exits.
9) In a double rainbow, the second bow is produced because droplets can have two reflections internally and get the same effect.
10) The droplets have to be the right size to get two reflections to work.

Althoughy Light looks colorless, it is made up of many colors - red, orange, yellow, green, blue, indigo and violet. These colors are known as the spectrum. When light shines into water, the rays of light refracts, or bends, at different angles. Different colors bend as different angles -- red bends the least and violet bends the most. When light passes through a raindrop at a certain angle, the rays separate into the colors of the spectrum - and you see a beautiful rainbow. A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicolored arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun. In a double rainbow, the second bow is produced because droplets can have two reflections internally and get the same effect. The droplets have to be the right size to get two reflections to work.

Conclusion
Rainbows consist of 7 different colors (also known as the spectrum) and is a meteorological phenomenon that is caused by reflection. Light looks colorless but in reality, it is really made up of many different colors. The rainbows take the form of a multicolored arc. In a rainbow, raindrops in the air act as tiny prisms and the droplets have to be the right size to get two reflections to work in a double rainbow.
