Two sinusoidal waves travel in a medium where the wave speed is 2 m/s, one to the right and the other to the left. We will concentrate on a region between x = 0 m and x = 8 m. a. The two figures below on the left are snapshot graphs of the two traveling waves at time t = 0 s. On the graph on the right, sketch the snapshot graph of the total wave at t=0 s. Ay (cm)

Two sinusoidal waves travel in a medium where the wave speed is 2 m/s, one to the right and the
other to the left. We will concentrate on a region between x = 0 m and x = 8 m.
a. The two figures below on the left are snapshot graphs of the two traveling waves at time t = 0 s.
On the graph on the right, sketch the snapshot graph of the total wave at t = 0 s.

g. Using your results, at what locations is the total wave always equal to zero? These locations
are called nodes.
h. Using your results, at what locations do the crests and troughs occur? These locations are
called anti-nodes.
