Question 1 Report

Rainbow formation is a natural phenomenon illustrating that white light

Answer Details
Rainbow formation is a natural phenomenon that occurs when white light is dispersed into its individual colours after passing through raindrops in the air. White light is made up of many different colours of light, each with its own wavelength. When the light enters a raindrop, it slows down and bends. This bending causes the light to separate into its individual colours, just like a glass prism would. The different colours then exit the raindrop at slightly different angles, creating a circular arc of coloured light in the sky. So, the correct answer is that rainbow formation illustrates that white light is dispersed into its constituent colours after rainfall.
