What is a Rainbow?

A rainbow is a beautiful arc of colours that appears in the sky after a rain shower. It happens when sunlight passes through raindrops and bends, creating a spectrum of colours like red, orange, yellow, green, blue, indigo, and violet. The rainbow seems like a colourful bridge between the Earth and the sky. It brings smiles and joy to people, filling them with wonder and happiness.

How Rainbows Form

Rainbows form when sunlight enters raindrops and bends or refracts as it passes through them. The light then reflects off the inner surface of the raindrop and exits, bending again as it leaves. This process causes the light to spread into its different colours, creating a circle of beautiful hues. 

Looking up, we see this circle as an arc in the sky. The colours in a rainbow are always the same: red on the outside, followed by orange, yellow, green, blue, indigo, and violet. Rainbows are a magnificent display of nature’s magic and bring awe and delight to all who witness them.

Colours of a Rainbow

A rainbow has seven colours: red, orange, yellow, green, blue, indigo, and violet. These colours form a spectrum of light that appears in the sky after rain showers when sunlight refracts and reflects in raindrops. The order of colours in a rainbow is always the same, with red on the outer edge and violet on the inner side. 

Each colour represents a different wavelength of light, creating the mesmerising display of hues we admire. A rainbow’s vibrant and enchanting colours have fascinated humans for centuries, inspiring art, mythology, and cultural significance worldwide.

The Science Behind Rainbows

The science behind rainbows lies in the process of light refraction and reflection. When sunlight enters raindrops, it bends or refracts due to the change in speed. The light then reflects off the inner surface of the raindrop and exits, bending again as it leaves. This bending separates the light into different colours, creating a spectrum of hues. 

When these colours are seen together, they form the beautiful arc of a rainbow. The colours in a rainbow are always the same: red on the outside, followed by orange, yellow, green, blue, indigo, and violet. Understanding this fascinating phenomenon adds to the wonder and appreciation of the magical world.
