A rainbow is an optical and meteorological phenomenon that causes a spectrum of light to appear in the sky when the Sun shines on to droplets of moisture in the Earth’s atmosphere. It takes the form of a single arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.

“Everyone wants happiness,
No one wants pain,
But you can’t have a rainbow,
Without a little rain”
Zion Lee

Rainbows can be observed whenever there are water drops in the air and sunlight shining from behind at a low altitude angle. The most spectacular rainbow displays happen when half the sky is still dark with raining clouds and the observer is at a spot with clear sky in the direction of the sun. The result is a luminous rainbow that contrasts with the darkened background.
