In this problem, we are given a string length and asked for the time it takes a wave to propagate in the string. Thus we'll need the expression:
Consider a string of total length L, made up of three segments of equal length. The mass per unit length of the first segment is μ, that of the second is 2μ, and that of the third μ/4. The third segment is tied to a wall, and the string is stretched by a force of magnitude Ts applied to the first segment; Ts is much greater than the total weight of the string. How long will it take a transverse wave to propagate from one end of the string to the other? Express the time t in terms of L, μ, and Ts.
