A rainbow occurs when there is sunlight and rain together.

A rainbow is an arc of colour in the sky that can be seen when the sun shines through falling rain. ... A rainbow is created when white light is bent (refracted) while entering a droplet of water, split into separate colours, and reflected back.rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.
