Eksplanasi
Almost everyone very likes a natural phenomenon called the rainbow. To the extent that a lot of people create an art work like song, cake, and the other work after seeing the beautiful colors of the rainbow. But, do you know how the phenomenon of the appearance of the rainbow happens?
Rainbow occurs because of the refraction of light. The sunlight that shines in between the rain drops is refracted by the rain drops. This process separates the white light of the sunlight into a spectrum of different colors.
The spectrum of colors are red, orange, yellow, green, blue, indigo, and violet. Or what we often memorize as the abbreviation "ROY G BIV / mejikuhibiniu.” Then the colors reflect in the back drops of rain, resulting the light which looks arched and becomes the rainbow
