Light enables us to see the world around us, and this sensation of vision has led to a fascination with the nature and properties of light. Light: A Very Short Introduction discusses early attempts to explain light; the opposing particulate and wave theories by scientists such as Isaac Newton and Christiaan Huygens; how light was recognized as an electromagnetic wave in the 19th century; and the 20th-century development of the quantum mechanics view of wave–particle duality. It also describes the many applications of light—domestic and scientific—including microwaves, DVDs, and lasers. It concludes by considering some of the most exciting new developments using quantum light sources in communications and computing.

Keywords: light; optics; quantum; quantum mechanics; speed of light; wave–particle duality
