Waves and Oscillations

Waves and Oscillations. Instructor: Prof. M. S. Santhanam, Department of Physics, IISER Pune. In this course, systematic theoretical background to the understanding of wave phenomenon in a wide spectrum of applications will be covered. Emphasis is placed on how theoretical ideas are applied in practice. (from nptel.ac.in)
