It has been recognised from the beginning that the most successful research of technology is predicated on a greater comprehension of scientific principles. We are delighted to introduce this Engineering Physics book to science and engineering students. This book covers the entire engineering physics syllabus as provided by Sant Gadge Baba Amravati University. This book includes theoretical questions, multiple choice questions, solved numerical problems, and practice numerical problems with solutions to help students to gain confidence and motivate them to study extensively. It is sincerely hoped that both students and teachers would find this book beneficial.
