Hey buddy,

Here's your answer ⤵️⤵️⤵️

The dispersion of light is the phenomenon of splitting of a beam of white light into its seven constituent colors when passed through a transparent medium. It was discovered by Isaac Newton in 1666. Newton discovered that light is made up of seven different colors. He passed a beam of sunlight through a glass prism. The glass prism split the light into a band of seven colors on his wall. He called this band of colors the 'spectrum'. Thus the spectrum is a band of seven colors which is obtained by splitting of white light by a glass prism. The order of colors from the lower end of spectrum is violet (V), indigo (I), blue (B), green (G), yellow (Y), orange (O), and red (R). The sequence of the 7 colors so obtained in a spectrum can be remembered by using the acronym "VIBGYOR".

The formation of rainbow is too based on the process of dispersion of light. It is the most enchanting example of dispersion of light which takes place naturally. Usually a rainbow of seven colors is seen in the sky just after the rain when the Sun is shining. The essential condition to see the rainbow is that the observer must stand with his back towards the sun, when seeing the rainbow. Actually after the rain, a large number of water droplets remain suspended in the atmosphere. These droplets of water function as small prisms. So, when the white light emitted by Sun falls on these water droplets, then the white light is split into seven colors and rainbow is formed.
