A rainbow is a meteorological phenomenon that occurs when sunlight is refracted, or bent, by water droplets in the air. It forms a circular arc of colors in the sky, usually appearing after rain showers or when there are water droplets in the air. The most common colors observed in a rainbow are red, orange, yellow, green, blue, indigo, and violet, with red being on the outer edge and violet on the inner edge. The order of colors is due to the varying angles at which sunlight is refracted and reflected within the water droplets.

Rainbows are a mesmerizing and captivating natural phenomenon that has fascinated people throughout history. They have been the subject of myths, folklore, and artistic representations in various cultures. Rainbows are not physical objects but optical illusions created by the interaction of sunlight and water droplets. The shape of a rainbow is always a circular arc, although it is often seen as a semi-circle due to the horizon blocking the lower part. Sometimes, if the observer is at a higher elevation, such as on a mountain, a full circle rainbow can be seen.

Rainbows are not only beautiful but also symbolic, often associated with hope, luck, and positivity. They have inspired awe and wonder in people of all ages and continue to be a source of joy and fascination. Whether seen in the sky after a rainfall or through the use of prisms or water spray, rainbows remind us of the beauty and diversity of the natural world around us.
