Instructions for problems 3 and 4 3 0.3 points For simplicity, from here on, we will remove the time-dependent behavior from our consideration by setting t = 0. Thus the following plots are only of y vs. x. Which of the graphs to the left correspond to each of the two initial waves you were given? You may find it helpful to plot these graphs on your own. If you do it by Below are several graphs. Questions 3 and 4 will reference these graphs. hand, you will gain even more insight. Plot A The graph that corresponds to the superstition of y1 and y2 is 1.5 The graph that corresponds to plot B y1 is 2.5 plot D. The graph that corresponds to plot A. y2 is 0.5 plot C. -1 plot E. -1.5 4 0.1 points Based on the graph you made for the superposition of y, and y2, would you consider the superposition to be simple harmonic oscillation? Why or why not. Plot B Yes. It keeps returning to the equilibrium position. 0.8 No. Waves and simple harmonic oscillation are two unrelated phenomena. 0.6 Yes. The pattern clearly repeats regularly. 0 No. It is not a simple sine or cosine curve. -0.2 -0.4 -0.6 WW y1 = sin(7x - 2xt) and y2 = sin( 2 + 2nt) -0.8 Plot C 1.5 0.5 .0.5 -1 -1.5 Plot D o in -D.5 -1.5 Plot E 1.5 0.5 -0.5 -1 -15
