We have seen a beautiful rainbow right after rain
Rainbow is formed after a rain in a direction opposite to that of sun
Let's see how is it formed
How is rainbow formed?
After rain, there are many tiny droplets of water still in the air
When sunlight falls on these droplets
These droplets act as tiny prisms
When sunrays fall on these droplets, the rays get first refracted, then internally reflected and then refracted again
Due to this different colors of sunlight are bent at different angles and we are able to see a spectrum in the form of a rainbow
