The book ``Oscillations and waves" is an account of one semester course, PHYSICS-I, given by the authors for the last three years at IIT, Kharagpur. The book is targeted at the first year undergraduate science and engineering students. Starting with oscillations in general, the book moves to interference and diffraction phenomena of waves and concludes with elementary applications of Schrödinger's wave equation in quantum mechanics. Authors have attempted a simplified presentation of the essential topics rather than taking a comprehensive and detailed approach. Since the area of waves and oscillations is ubiquitous in science and engineering, authors hope that this book would be beneficial for the students of Indian colleges and universities.
The authors are indebted to Prof. G. P. Sastry for his pedagogy and unstinting encouragement. The authors are also indebted to Prof. Anushree Roy and Prof. Tapan K. Nath for providing us with data and figures for Raman effect and X-ray diffraction respectively.
Authors apologise in advance for the misprints.
