Originally published as part of the renowned Bergmann-Schaefer textbook series on experimental physics, this is a revised and extended version of the 9th edition of Volume 3. In it, eminent experimental physicists provide an in-depth treatment of both light and particle optics from a primarily experimental perspective. Each author includes the necessary theoretical framework needed to understand the various phenomena, then introduces readers to the major experimental features. Authoritative and comprehensive, this volume offers a wealth of information and sets the standard by which all similar texts will be judged.
