Consider a system of three connected strings, S1, S2 and S3 with uniform linear mass densities μ kg/m, 4μ kg/m and 16μ kg/m, respectively, as shown in the figure. S1 and S2 are connected at the point P, whereas S2 and S3 are connected at the point Q, and the other end of S3 is connected to a wall. A wave generator O is connected to the free end of S1. The wave from the generator is represented by y=y0cos(ωt−kx) cm, where y0, ω and k are constants of appropriate dimensions. Which of the following statements is/are correct:
