Rainbow is a phenomenon observed mostly in the Earth's atmosphere when the [[light|visible light]] from the [[Sun]] [[reflection|reflects]] and [[refraction|refracts]] inside the raindrops that are opposite to the Sun. The phenomenon can be observed as an arc if an observer looks at these raindrops from an angle of 42°. The formation of the arc is the result of [[dispersion]] of the visible light into its individual components — Red, Orange, Yellow, Green, Blue, Indigo, and Violet (ROY G BIV). | Rainbow is a phenomenon observed mostly in the Earth's atmosphere when the [[light|visible light]] from the [[Sun]] [[reflection|reflects]] and [[refraction|refracts]] inside the raindrops that are opposite to the Sun.
