This wavelength of light forms a ribbon of parallel lines, each nuanced color with a color next to it. This band is called the color spectrum. In the color spectrum, the red lines are always on one side and blue and violet on the other, and this is determined by the difference in wavelength. Rainbow is a natural phenomenon that is so impressive. This phenomenon often appears after rain. Rainbow is an arc spectrum which is so large and occurs because the drops are r...
