In this chapter we shall study the linear wave equation in one space variable. Solutions of this equation have many features in common with the first-order equation u t + cu x = 0 that we studied in Chapter 2. The linear wave equation arises in many contexts which include gas dynamics (acoustics), vibrating solids, and electromagnetism.
