Rainbow High in The Sky

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 multicoloured arc, with red on the outer part of the arc and violet on the inner section. Rainbows can be observed whenever there are water drops in the air and sunlight shining from behind at a low altitude angle.
