### Course description and aims

Oscillations and waves are the most fundamental motions in nature and are observed ubiquitously in the real world. In this course, we learn basic concepts and properties of oscillations in various oscillatory systems ranging from a single pendulum to continuous systems. We also consider oscillations and waves in actual physical systems such as elastic waves and electromagnetic waves. Learning the principles of oscillations will provide us with a general approach to oscillatory phenomena in various areas of science and technology and will also be useful in applying oscillatory phenomena for practical purposes.

### Student learning outcomes

By the end of this course, the students will be able to:
1) Understand the basic concepts of oscillations and waves.
2) Learn the systematic approach to oscillations and waves.
3) Explain the characteristics of various kinds of oscillatory phenomena.
