A rainbow is a meteorological phenomenon that occurs when sunlight is refracted, or bent, and reflected inside raindrops in the air. It takes the form of a multicolored circular arc in the sky. Rainbows are typically seen when there are rain showers or other sources of water droplets in the air, such as mist, spray, or fog.
The process of the formation of a rainbow begins when sunlight enters a raindrop. The sunlight is made up of different colors, each with a different wavelength. As the light enters the water droplet, it slows down and bends, or refracts, due to the change in the density of the medium. The different wavelengths of light are refracted by different amounts, causing them to separate and spread out.
Upon entering the droplet, the light is partially reflected off the inner surface of the droplet and then refracted again as it exits the droplet. This refraction and reflection within the droplet cause the light to undergo further separation and dispersion. The different colors of light then exit the raindrop at different angles, forming a circular arc of colors.
The most common type of rainbow, known as a primary rainbow, is the one that people are most familiar with. It displays a sequence of colors from red on the outer edge to violet on the inner edge, with orange, yellow, green, and blue in between. The primary rainbow appears as an arc, with its center opposite the sun in the sky. Sometimes, a secondary rainbow can be seen outside the primary rainbow, appearing as a fainter and wider arc. In the secondary rainbow, the colors are reversed, with red on the inner edge and violet on the outer edge.
Rainbows are not physical objects, but rather optical illusions created by the interaction of light with water droplets. They are observed from the observer’s perspective, so each person sees their own unique rainbow. The exact colors and intensity of a rainbow depend on factors such as the size of the raindrops, the angle of the sunlight, and the position of the observer.

An arch of colours visible in the sky, caused by the refraction and dispersion of the sun’s light by rain or other water droplets in the atmosphere. There are basically seven colours in the rainbow The patterns of the colours are called spectrum, starts with the red on the outside and ends with violet on the inside
There are basically seven colours which are as follows:
Red, Orange, Yellow, Green, Blue, Indigo, Violet.
A rainbow is created when the light is bent, while entering in a droplet of water, split into seperate colours and reflected back.
A rainbow is basically round like a circle. On the ground bottom part is hidden. It is a very natural phenomenon.

A rainbow is a meteorological phenomenon that appears as a multicolored arc in the sky. It is caused by reflection, refraction, and dispersion of light in water droplets, resulting in a spectrum of colors. Rainbows usually appear when sunlight shines through raindrops in the atmosphere.<div>
