VIBGYOR And How It Is Formed In The Rainbow
VIBGYOR is an acronym for the colours violet, Indigo, blue, green, yellow, orange and red. These are the colours found in sequence in the rainbow. The rainbow consists of these seven colours.
One can witness a rainbow after the rain. The Other necessary condition for a rainbow to be formed is the presence of Sunlight while it is raining.
The formation of a rainbow takes place due to a simple effect known as refraction. While it is raining, thousands of water droplets refract the rays of sunlight coming to them. This results in the formation of a rainbow.
The colour sequence in the rainbow is similar to the sequence in the acronym VIBGYOR.

The phenomenon of splitting of white light into its component colours when it passes through a Prism is called dispersion. The component colours are the VIBGYOR ( V-violent, I-indigo, B-blue, G-green, Y-yellow, O-orange, R-red). These colours are known as the spectrum. When a beam of white light is passed, 7 colours are obtained. When these seven colours are obtained from the beam of light, it is known as a spectrum of light. This phenomenon includes the refraction of light when it passes through the prism,m, which is a transparent refractive medium.
As we know, a rainbow consists of these seven colours. But in the formation of the rainbow, the prism is replaced by tiny droplets, and the white beam of light is replaced by the sunlight in this process. Then, Dispersion of Sunlight happen through the tiny water droplets, which act as a transparent refractive medium present in the atmosphere. This whole process results in the formation of a rainbow.
