24 Facts (And 24 Stories) About Rainbows

Rainbows are exquisite and rare. These beautifully arched, colorful formations are a visual treat. And they are almost magical, hypnotizing its viewers. While everyone is drawn to the splendid beauty of rainbows, the science behind rainbows is equally fascinating.

How is a Rainbow Formed?

Rainbow is an optical phenomenon, much like Lunar Halo. For rainbow to be seen, three conditions must be met:

It should be raining
Sun should be visible
The observer/viewer must be in between the sun and rain

Rainbow is formed when sunlight is refracted that is bent while passing through the water droplets. The raindrops bend the light acting like tiny prisms, splitting white light of the sun into its individual, different colours.

White light is made of a combination of colours, the ones we refer to as VIBGYOR – the colours of rainbow. As sunlight passes through the water drops, it is bent at different angles, giving rise to the spectacular phenomenon of the rainbow.
