In orderto see a rainbowyou’ll need two ingredients : sunlight and raindrops . Sunlight is a mixture of colors . When it passes through a meth prism , or dip of water , some of the light is bent , or refract , more than other portions . Light leave the prism spreads out into a uninterrupted dance band of vividness called a spectrum . color go from red , which is bent least , through orangish , yellow , green , and blue all the path to reddish blue , which is bent the most . This is what happens when sun passes through water droplet in the atmosphere , with red on the exterior of the rainbow arch and reddish blue on the interior .
Sometimes a secondary curtain call forms outside the primary , giving the facial expression of a double rainbow . The secondary bow shape with the colors reversed : red on the inside , violet on the outside .
