Waves and Oscillations I

This is an introductory course on wave and oscillation physics. Wave phenomena are used in all of our communication devices, musical instruments, and technological equipment. Theoretical frameworks will be presented in this course. There will be a background to the study of wave phenomena in a wide range of applications covered. The application of theoretical principles in practice is emphasized.
