Includes bibliographical references and index

Modern Physics introduces the fundamental concepts that transformed our understanding of the physical universe beyond classical physics. The book explores the development of quantum mechanics and relativity, explaining the behavior of matter and energy at atomic, subatomic, and cosmic scales. Major topics include wave-particle duality, atomic structure, quantum theory, nuclear physics, elementary particles, solid-state physics, and the basics of cosmology. By combining theoretical explanations with practical examples and problem-solving techniques, the book helps students understand how modern physics forms the foundation of today's scientific and technological advancements, including semiconductors, lasers, and nuclear energy. It is intended to provide learners with a strong conceptual framework and analytical skills for further study in physics and engineering.
