PREFACE: It gives us immense pleasure to presenting "Engineering Physics" book for the students of engineering graduate to fulfill thrust of physics with its role in technology. This book has been written in simple language and comprehensive manner to keeping sense to create interest of students in physics. The main focus has been given on enhance the basic concept rather than the information, well labelled diagrams, solved numerical with important formula. We are confident this book is milestone in the journey of learning physics towards engineering approach. We have deeply thanks to our students, colleague, family members and all those who directly or indirectly supported us in this project.
