# Chapter 17: Waves and Oscillations

We have just considered general oscillatory behavior. We noticed that the common theme was that the motion could be described as periodic. We now consider a different type of periodic or oscillatory motion called wave motion. We begin with waves traveling in one dimension, but we will then consider waves in two and three dimensions, such as sound, in the next chapter.
