Preface
Optics is one of the most fascinating and rapidly evolving branches of physics that deals with the study of light, its behavior, and its interaction with matter. The subject forms the foundation for numerous technological advancements that shape modern society, including imaging systems, optical communication, laser technology, and photonic devices.
This book, Fundamentals of Optics for Engineering Physics, is designed to provide a clear, systematic, and application-oriented understanding of both Geometrical Optics and Wave Optics, along with modern topics such as Lasers and Fiber Optics. The content is organized in a logical sequence starting from the fundamental nature of light to advanced optical communication systems, making it suitable for undergraduate engineering students.
Each unit is presented in a simple and concise manner, supported with relevant explanations and diagrams to enhance conceptual clarity. Emphasis is given to physical interpretation of principles, mathematical formulations where necessary, and real-world applications in engineering and technology.
The objective of this book is to bridge the gap between theoretical concepts and practical applications, enabling students to develop a strong foundation in optics and its engineering relevance. It is hoped that this book will be useful not only for academic examination purposes but also for inspiring further interest in research and technological innovation in the field of optics.
Suggestions and constructive feedback from readers for the improvement of this book will be highly appreciated.
