This book is structured keeping in view the objective of the Engineering Physics-I course. The content of the book is built with a student-friendly approach and aims to set a benchmark for a modern approach to the fundamental topics. In each chapter,
the fundamental concepts of physics is delineated and then linked to their applications. The book consists of five chapters and
Lab consisting of six experiments. This book covers the topics such as crystal physics, properties of matter and thermal physics, quantum physics, acoustics and ultrasonics, and photonics and fiber optics.
