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
