Engineering Physics is designed as a textbook for first year undergraduate engineering students. The book comprehensively covers all relevant and important topics in a simple and lucid manner.Beginning with a detailed discussion on optics, the book goes on to discuss waves and oscillations, architectural acoustics and ultrasonics in Part I. The basic principles of classical mechanics, relativistic mechanics, quantum mechanics and statistical mechanics are included under Part II. Electromagnetism-related topics, namely dielectric properties, magnetic properties and electromagnetic field theory are explained under Part III. Part IV provides an in-depth treatment of topics such as X-rays, crystal physics, band theory of solids and semiconductor physics. It also includes a discussion on conducting and superconducting materials. Topics such as nuclear physics, radioactivity and new engineering materials and nanotechnology are presented in the last section of the book. The text also contains appendices on SI units, important physical and lattice constants, periodic table, and properties of semiconductors and relevant compounds for ready reference.
