A small beautiful video for grade 6 (KS4) kids, explaining the science behind rainbow formation.When the sunlight falls on a raindrop, the light is bent because the light is moving from one medium(air) to other medium( water). Drops of rainwater disperse light in a similar way as a prism.. When the light comes out of the water droplet, the sun's rays (white light) gets split into light of different wavelengths (colors). Each raindrop behaves like a prism, dispersing white sunlight into its seven component colors ,hence a rainbow is formed.
