Consider a system of three connected strings, \( S_1, S_2 \) and \( S_3 \) with uniform linear mass densities \( \mu \, \text{kg} / \text{m} \), \( 4\mu \, \text{kg} / \text{m} \) and \( 16\mu \, \text{kg} / \text{m} \), respectively, as shown in the figure. \( S_1 \) and \( S_2 \) are connected at the point \( P \), whereas \( S_2 \) and \( S_3 \) are connected at the point \( Q \), and the other end of \( S_3 \) is connected to a wall. A wave generator \( O \) is connected to the free end of \( S_1 \). The wave from the generator is represented by \( y = y_0 \cos(\omega t - kx) \, \text{cm} \), where \( y_0 \), \( \omega \) and \( k \) are constants of appropriate dimensions.
