VIBGYOR is an acronym for the word violet Indigo blue green yellow orange and red. These are the colour found in sequence in the rainbow. The rainbow consists of these seven colours.
One can witness the 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 rainbow take place due to simple effect known as refraction. While it is raining, the 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.
