But, to appreciate the roots of quantum physics an understanding of 'light' is imperative. Although light is colloquially used to denote that to which our eyes are sensitive, it is now recognized that visible light is only a tiny fraction of a continuous spectrum also containing 'invisible light'. The entire spectrum is referred to as electromagnetic radiation. Often when physicists talk about light they are really talking about the whole spectrum, for example references to the speed of light. The task, then, before proceeding with the main topics of this book, is to provide a brief exposition of the history of our understanding of the nature of light from the end of the 19th century. To accomplish this we will also have to acquire a basic understanding of electricity and magnetism.Read More
