Equation 12.1 describes a wave that is traveling to the right, and Equation 12.5 corresponds to a wave of the same frequency and wavelength that is moving to the left. Show that the sum of these two waves gives a standing wave. That is, show that this sum has nodes and anti nodes as sketched in the standing waves in Figure 12.24.
