Fundamental of Wave and Optics

Our world is filled with oscillations in which objects move back and forth repeatedly. This book is prepared for University physics undergraduate and graduate students. It mainly focuses on vibration and different types of vibrations, waves and different types of waves, superposition principle and explains how superposition waves formed, the nature and properties of light, electromagnetic spectrum, interference and diffraction of light, optical devices, and how they work. Especially undergraduate students(especially in Ethiopia) get special advantages from this book.
