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
