Beauty Behind Rainbows
A rainbow to me is the most spectacular light show on earth given by nature. It’s a beautiful sight to see a rainbow after a rainy period during the day. Have you ever wondered if there is a pot of gold at the end of a rainbow? Maybe you have or maybe you even tried to find it. Why do you think rainbows may appear after it rains? In this paper you will find out how rainbows are formed, the colors of the rainbow, and even interesting facts.

You can never reach the end of a rainbow, where a pot of gold supposedly awaits. As you move, the rainbow that your eyes see moves as well, because the raindrops are at different spots into the atmosphere. Rainbows have no end because they are circles. You can see the complete circle of a rainbow from an airplane. There is no reason why you can’t see the end of a rainbow from the ground. For you see a rainbow, raindrops have to be falling somewhere in front of you, and once again the sun has to be behind you. That way the raindrops can reflect the light from the sun back to your eyes. You see that light as colors of the rainbow because light from the sun is made up of all possible...
