Primarily intended for the undergraduate students of all branches of engineering, this textbook provides a sound understanding of the fundamental concepts and principles of physics in a simple and easy-to-understand language. Organized in 18 chapters, the book exposes students to the fundamentals of oscillations and waves, interference of light, diffraction, polarization, optical instruments, laser, fibre optics, mechanics and special theory of relativity. Apart from giving a detailed theoretical analysis of these topics, it also provides a deep insight on various advanced topics such as acoustics, ultrasonics and nanotechnology, along with their applications. The pedagogical aids such as solved numerical problems and review questions are also included at the end of each chapter. Key Features :  Numerous solved examples to stress on the conceptual understanding  Chapter-end model questions to probe a student's grasp of the subject matter  Chapter-end objective type questions (with answers) for self-evaluation by the students
