Here is a clear, accurate introduction to the science of light - the radiation we can see.

And here too are the many kinds of radiation we cannot see — X-rays that save countless lives; ultraviolet rays that detect crimes; infra-red rays that direct a guided missile to an unseen target; television waves that bring entertainment into our homes; and many more.

In this book Dr. Ira M. Freeman, Professor of Physics at Rutgers University, discusses both the scientific theory of radiation and the practical applications of the expanding knowledge in this field. Included are the latest exciting developments in lasers, radio astronomy, and even "op art".
