Scientific discovery of three primary colors of light

/kloc-Issac Newton, a great scientist in the 0/8th century, discovered the famous three laws of mechanics, which not only made outstanding achievements in mechanics, but also left a valuable wealth for future generations who like photography, that is, the optical color theory. He laid the scientific foundation of modern color research.

Newton discovered the mystery of the color of light. After systematic observation and research experiments, he finally confirmed that when a beam of white light passes through a prism, it will be refracted twice, and the result is that the white light is decomposed into seven regular colored rays. These seven colors are red, orange, yellow, green, blue, indigo and purple in order. This is what people often call "seven-color light". And these seven kinds of light will be combined into a beam of white light after being reversely refracted by the prism. So, 1666, Newton published a theory-"color is in light". Newton's prism experiment was later called the famous "dispersion experiment" This research achievement is also the "spectral theory" that Goethe, a great German writer, has been strongly refuting for decades after Newton.
