Abstract
Anyone who has looked at a rainbow has surely found them to be interesting and beautiful. For a long time few people understood what they saw. It was Sir Isaac Newton (1642–1727) who demonstrated what causes rainbows and some of the deeper characteristics of light. Newton took a glass prism and allowed a sliver (light through a small slit) of light to fall on it. What was seen on the other side of the prism was a rainbow of colors. White light was broken down into rainbow colors (Fig. 1.1).
