About Rainbow
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. 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 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 seven colours in the rainbow. The patterns of the colours are called a spectrum, starting with red on the outside and ending with violet on the inside
There are seven colours, which are as follows:
Red, Orange, Yellow, Green, Blue, Indigo, Violet.
A rainbow is created when the light is bent while entering a droplet of water, split into separate colors, and reflected back.
A rainbow is round like a circle. The 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.
The colors of a rainbow typically appear in the order of red, orange, yellow, green, blue, indigo, and violet (ROYGBIV). Each color corresponds to a different wavelength of light, with red having the longest wavelength and violet the shortest.
Rainbows are often seen as beautiful and awe-inspiring natural occurrences, and they have been the subject of myths, legends, and cultural symbolism throughout history.

A rainbow is a meteorological phenomenon that appears as a multicolored arc in the sky, typically observed when raindrops or other water droplets are present in the air and sunlight shines through them. It forms a circular or semicircular shape, with the center of the circle or arc appearing opposite the direction of the sun.
The formation of a rainbow involves the refraction, reflection, and dispersion of sunlight within the water droplets. When sunlight enters a raindrop, it refracts (bends) as it moves from air into the denser water. Upon entering the droplet, the light undergoes multiple internal reflections, bouncing off the droplet’s inner surface. Some of the light is also refracted again as it exits the droplet.
As the light is internally reflected and refracted, it is also dispersed into its component colors (red, orange, yellow, green, blue, indigo, and violet) due to differences in the wavelengths of each color. When the dispersed light exits the droplet, it forms a spectrum of colors, creating the familiar band of colors that we perceive as a rainbow.
The size and intensity of a rainbow can vary depending on factors such as the size of the raindrops, the angle of sunlight, and the observer’s position. Sometimes, a double rainbow can be observed, with a fainter and broader arc appearing outside the primary rainbow. Double rainbows occur when light undergoes an additional reflection within the raindrops, resulting in a secondary arc with a reversed color order.
