c A ray of light is divided into its constituent colors by the first prism (left), and the resulting bundle of colred rays is reconstituted into white light by the second. Our modern understanding of light and color begins with Isaac Newton (1642-1726) and a series of experiments that he publishes in 1672.
During the 1660’s, Newton, an English physicist, started some experiments with sunlight and prisms to know more about the optic field. He passed sunlight through a prism and separated the light beam into various colours. Once he did it, he discovered and understood that this could happened because every different ray of colour is diverged by the glassy prism by a different amount. Consequently, he could conclude that white light passes through a translucent medium, such as air, into another like glass, the components are glanced the first-time up t their colour and when they go back to air they do it again. This created the spectrum with the rainbow colours.
Hydrocarbons are compounds of hydrogen and carbon. Photosynthesis is a process of nutrition in plants. Thunder is a sound. Lightning and electric eels are electrical phenomena in nature.
It can be said that the change is a chemical change. The green substance on the surface is copper oxide. It is a compound composed of the copper of the statue and the oxygen in the air.
