What Are the Colours of the Rainbow?

Colours Of The Rainbow: Rainbows have seven colours in total. The colours of the rainbow always appear in the same order: Red, Orange, Yellow, Green, Blue, Indigo, and Violet. An easy way to remember the order of the colours is using ROYGBIV, which is an acronym for Red, Orange, Yellow, Green, Blue, Indigo, and Violet.

What Is a Rainbow?

A rainbow is a colourful arc that appears in the sky when the sun shines through raindrops. As the sunlight enters the raindrop, it bends or refracts, which creates colour. It reflects off the inside of the raindrop and then bends again as it leaves the raindrop, creating the rainbow.

The rainbow's different colours blend together to produce a smooth transition from one to the next.

What Causes a Rainbow?

The cause of a rainbow is sunlight and rain. Rainbows generally appear when the sun comes out after a rain shower, and you are looking at the rain in front of you, with the sun shining from behind you.

Why Are There Seven Colours?

These seven colours form the visible light spectrum. Long ago, the scientist Isaac Newton split white light into seven colours using a glass prism. He picked seven colours, as he believed seven was an important number in music, astrology and ancient traditions.

Fascinating Facts About Rainbows:

Order: The colours show up in the same order every time. Red is at the top, and Violet is on the bottom.

Double: Sometimes, you'll see a second rainbow above the rainbow. It will be fainter, and its colours will be reversed.

No End: Rainbows are usually full circles; we typically only see the arc. From an aeroplane, people sometimes are able to see the full rainbow, or circle!

Mythology: Many cultures believe rainbows are magical. In Norse mythology, there was a rainbow bridge that connected the Earth to the gods.

Pot of Gold: Of course, the idea that there is a pot of gold at the end of the rainbow is just a fun myth. Rainbows do not have real ends!

Science: Each raindrop makes its own little rainbow. The one that we see is really just the combination of millions of these little rainbows!

What Makes Rainbows So Special?

Rainbows are more than just light and rain. They represent hope, peace, beauty, and wonder. They remind us that something magical can appear after a storm and remind us that nature never stops surprising us!
