Rainbow Formation

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
