Isaac Newton was creative in his use of prisms to show how white light is actually made up of multiple colors. He used logic in the way he presented his arguments rhetorically in order to convince readers of the correctness of his conclusions.
Newton was not the first to experiment with passing light through prisms to determine how light works. French philosopher Rene Descartes had done prism experiments of his own. But Descartes had thought that passing through a prism actually modified the light in order to produce the color spectrum. Newton correctly understood that when light refracted through the prism, it revealed the range of colors that were naturally in the light. He then used a second prism, blocking all but one color, to show that a single color passing through a prism was not modified in color. He also showed--by positioning the second prism differently--how the multiple colors of light could be recombined into white light again.
Newton's 1672 paper on light refracting through prisms established his reputation as a scientist. He continued to study light throughout his scientific career, publishing a larger work in 1704 on <em>Opticks </em>(as they spelled "optics" then).
Answer:
I THINK it should be A
Explanation:
Heres what I found:
During 1989 and 1990, the Berlin Wall came down, borders opened, and free elections ousted Communist regimes everywhere in eastern Europe. In late 1991 the Soviet Union itself dissolved into its component republics. With stunning speed, the Iron Curtain was lifted and the Cold War came to an end.
The Versailles Treaty was signed on June 28, 1919 and was known to be the principal peace treaty signed after the First World War. This document was signed by the powers that formed the Triple Entente and by Germany. It was considered by historians as the “peace of the winners”, since the nations that had won.
The Versailles Treaty was one of the peace agreements signed with the end of the First World War. This conflict lasted from 1914 to 1918 and was the first major clash that marked the history of mankind. The First World War was the result of a combination of factors that contributed to create a climate of tension that broke out in 1914.
This war was the result of disputes caused by imperialism and rivalries motivated by revanchism and nationalism. The strengthening of rivalries and tensions in Europe in the beginning of the 20th century motivated nations to form military alliances and to invest in the production of weapons.
