Consider a string of total length , made up of three segments of equal length. The mass per unit length of the first segment is , that of the second is , and that of the third . The third segment is tied to a wall, and the string is stretched by a force of magnitude applied to the first segment; 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 in terms of , , and Ts.
Strings with different mass per unit length attached together. Time taken by the wave is calculated.
