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 , that of the second is 2, and that of the third /4. The third segment is tied to a wall, and the string is stretched by a force of magnitude T applied to the first segment; Ts is much greater than the total weight of the string. Part A 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, , and Ts. View Available Hint(s) Hint 1. How do the segments differ? Consider each segment of the string seperately. Which quantities are the same and which are different in each of the three segments? View Available Hint(s) Both the wave velocity and the tension in the string are the same in all three segments. Both the wave velocity and the tension are different in the three segments. The wave velocity is the same in each segment but the tension is different. The tension is the same in each segment but the wave velocity is different. Submit Previous Answers Correct Consider each segment of the string separately. Calculate the time it takes the wave to pass through distance L/3 using the relevant velocity for transverse waves on a string. Then sum the three separate times obtained. Be careful to use the correct values for the mass per unit length of each segment. Also it is recommended that you collect similar variables to make entering the answer easier. Hint 2. Example: speed in the second segment Find v2, the speed of propagation of the wave in the second segment of the string described in the problem introduction. Express the wave speed on the second segment in terms of Ts, , and any constants. View Available Hint(s) Hint 1.
