" RAINBOW "
* Introduction:-

A rainbow is a captivating natural phenomenon that has fascinated people for centuries. It is not only a subject of  scientific interest but also a source of inspiration in art and literature. This beautiful arc of colors appears in the sky under specific conditions, making it a rare and delightful sight.
Poetically, rainbows have been symbols of hope, promise, and beauty. They often appear after a storm, leading to the popular phrase “there’s a rainbow after the storm,” symbolizing better times after difficult periods. The vibrant colors and the perfect arc shape have inspired countless poems, songs, and artworks throughout history.
There are several special types of rainbows. A double rainbow occurs when light reflects twice inside water droplets, creating a second, fainter arc outside the primary one with reversed colors. Supernumerary rainbows are closely spaced, faintly colored bands inside the main rainbow, caused by the interference of light waves.
Rainbows can be seen all over the world, but certain places provide particularly stunning views. Waterfalls, like Niagara Falls, often produce rainbows due to the constant mist in the air. High-altitude regions, such as the mountains of Hawaii, are also prime locations for observing these natural wonders.
Rainbows are typically seen when the sun is low in the sky, such as early morning or late afternoon. To witness a rainbow, you need the sun behind you and rain falling in front of you. The best vantage points are wide-open spaces where the sky is unobstructed.

*Discovery of rainbow:-
Credit goes to Isaac Newton. Through a series of experiments with prisms and sunlight, Newton discovered that white light is made up of many different wavelengths, or colors.

* Scientific reason:-
Scientifically, a rainbow forms when sunlight passes through raindrops. The light bends, or refracts, as it enters the raindrop, reflects off the back of the drop, and then refracts again as it exits. This process splits the light into its constituent colors: red, orange, yellow, green, blue, indigo, and violet. The arrangement of these colors is always the same, with red on the outer edge and violet on the inner edge.

* Conclusion:- 
In conclusion, rainbows are a splendid blend of  science and beauty. Whether understood through the lens of physics or appreciated for their aesthetic and symbolic value, they continue to enchant and inspire people everywhere.
