Engineering Physics forms the bridge between the fundamental principles of science and their practical applications in engineering innovations. This multi-author volume, Engineering Physics, is conceived as a comprehensive textbook tailored for undergraduate students of all branches of engineering. The collaborative expertise behind this book brings together academic insight and instructional clarity to ensure an ideal balance between theory and practice. The contributors, representing diverse areas of specialization in physics and engineering education, have pooled their collective experience to produce a text that is pedagogically rich, technically sound, and aligned with contemporary curricula.​
The book begins with a strong conceptual foundation in mechanics, waves, and oscillations, emphasizing analytical reasoning and problem-solving. Subsequent chapters progressively explore optics, electromagnetism, quantum physics, semiconductor physics, and materials science, reflecting the dynamic integration of classical and modern approaches. Special attention has been paid to emerging fields such as nanotechnology, lasers, and fiber optics, which are crucial for current and future technological applications.​
Each chapter was prepared with deliberate pedagogical intent—beginning with learning objectives and followed by detailed theoretical explanations, illustrative examples, and review problems at the end. Mathematical formulations are accompanied by physical interpretations to strengthen conceptual understanding. The illustrative problems are carefully graded in difficulty to benefit both quick learners and those needing step-by-step guidance.​
We, the authors, have designed the content to align with standard syllabi prescribed by leading Indian and international universities. Integration of recent advancements and experimental techniques provides the student with a comprehensive view of the evolving engineering landscape. For ease of study and quick revision, formula sheets, numerical examples, review questions, and objective tests have been included. It is our intention that this book serves equally well as a textbook for first-year engineering students and a reference for advanced learners seeking conceptual reinforcement.​
Our collective gratitude goes to the academic community—students, teachers, and reviewers—whose continuous dialogue and constructive suggestions have shaped the refinement of this book. The collaborative effort across departments demonstrates how interdisciplinary understanding enriches the teaching of physical sciences to engineers. We hope this book motivates readers to discover the elegance of physics and its profound implications in the domains of technology and innovation.​
