Light and Sound

This series explains and illustrates the science of physics and its everday applications. Physics is concered with matter - the stuff from which everything is made - and with energy in all its forms. Both light and sound are forms of energy and this book explains the properties of light, including where it comes from, how it travels, and how it is reflected and refracted. The properties of sound are also explored; what is it and how is it made and recorded? Explanatory diagrams and simple practical experiments help to provide a perfect introduction to this fascinating subject.
