There is hardly can be found a man who have never seen rainbows in his long life. Rainbows are the symbol of the beauty & arts of the nature. Have you guys ever thought that what is rainbow? Why we see it?? **Yes, Science can explain the fact easily and It's not less beautiful than the colours of rainbows.** ![20190729_183720.jpg](https://files.steempeak.com/file/steempeak/rana2423/r6X709Qu-20190729_183720.jpg) ### What is rainbow?? A rainbow is an arc which is multicolored and It's appear in the sky while the sunlight hits water drops. On that time in the sky we can see a curve of colours, It is called rainbow. ### A rainbow can only be formed when the conditions given below are fulfilled. 1. The sun must have to be lightfull and not to be obscured by clouds. 2. The wind blowen from the opposite side of the sun must have to carry a lot of water droplets. 3. On that time the sun must have to be quite low in the sky. It's a must necessary condition to be formed a rainbow. There is a remarkable place.*Bellow the 42° is a good attitude.* ![20190729_183718.jpg](https://files.steempeak.com/file/steempeak/rana2423/CHyrCnvF-20190729_183718.jpg) Rainbow depands on the three kinds of dancing of lights. It's The reflection of lights, The dispersion of lights, and the refrection of lights. **The water droplets are very small but to much effective to formed a rainbow. I can be worked as a morrow. In which the sunlight will dropped and reflect.** Reflection is the primary condition of forming a rainbow. After that there must have to act dispersion. It is one of the most important part to forme a rainbow because without the full formed of three part fulfilled a full rainbow will never be formed. ![20190701_183844.jpg](https://files.steempeak.com/file/steempeak/rana2423/p3PRtPMt-20190701_183844.jpg) **The color of sunlight is white, When it comes into the water droplets, on that time the dispersion is occoured. The lights come into the droplets and break down into several colors, this happened when the sunlight come into the water droplets and when it's going out from it.** After finishing this process another way to come is refrection. It's the last stage and it's also another important part to be formed rainbow and it's the last one obviously. **While Going out from the water droplets the sunlight make it self reflect into the water droplets. The reflection is increasing it's color and deviding it's several colors. Each color devide into different directions, For this reason we see Various colors in a rainbow.** ![20180714_191306.jpg](https://files.steempeak.com/file/steempeak/rana2423/DSY1mRK3-20180714_191306.jpg) This is the full formation of a rainbow. In this The rainbow is formed in the sky and we see it. This blog was just about the formation of rainbow.Hopefully I will make another blog on rainbow and On that blog I will try to write about The duration of rainbows and why we watch seven colors in rainbow. Why the rainbow turned into a curve.?... ### Hopefully you guys enjoyed my blog and I just tried to give some information as I always try. You all know that science is a mestry, So if we want to know the nature we do firstly have to understand the conditions and we have to invent ourselves through the nature. Just take it on your mind that all the answers of your questions are hidden into the nature. You just have to discover it. ![20190727_191028.jpg](https://files.steempeak.com/file/steempeak/rana2423/1Lfg1p6x-20190727_191028.jpg) ### Special Thanks Thanks to [@azizbd](https://steemit.com/@azizbd) for his kind deligation.
