How do Rainbows Form?

Rainbows are a beautiful phenomenon to take in! The conditions need to be just right and when they are it is always exciting to enjoy the view!

But why do rainbows form in the first place? What conditions are needed to form a rainbow?

This can be a topic fit enough for an entire doctoral thesis, but we are keeping things simple. In short, the sun lights rays need to be passing through water droplets at the precise position for the light to refract out to achieve the rainbow effect. This effect is the same as light passing through a prism and separating into its respective colors. [See Pink Floyd’s Dark Side of the Moon album cover for example]
