Principles of Optics

Optics is a branch of physics that deals with the study of light and its behavior. It comprises the study of the generation, propagation, interaction, and detection of light, including its interactions with matter and its properties such as reflection, refraction, diffraction, and polarization. It elucidates the behavior of visible, ultraviolet, and infrared light. Classical optics comprises two primary branches: physical optics, which views light as propagating in waves, and geometric optics, which perceives light as traveling in straight lines known as rays. Modern optics delves into the electromagnetic and quantum attributes of light. Optical principles find application in diverse fields, including engineering, astronomy, photography, and medicine. Through this book, constant effort has been made to make the complex subject of optics easy and informative for the students. The topics covered in it deal with the core aspects of the subject. Coherent flow of topic, student-friendly language and extensive use of examples make this book an invaluable source of knowledge.
