## Principles of Engineering Physics - 1

This is a textbook for an introductory course in engineering physics. It provides a coherent treatment of the basic principles and theories of engineering physics and offers a balance between theoretical concepts and their applications. Beginning with a comprehensive discussion on oscillations and waves with applications in the field of mechanical and electrical engineering, it goes on to explain basic concepts such as Huygen’s principle, Fresnel’s biprism, Fraunhofer diffraction and polarization. All chapters are interspersed with rich pedagogical features such as solved problems, unsolved exercises and multiple choice questions with answers. It will help undergraduate students of engineering acquire skills for solving difficult problems in quantum mechanics, electromagnetism, nanoscience, energy systems and other engineering disciplines.
