A guitar string of negligible mass and length L, attached at one end, is tensioned by a constant force T. A pulse is generated at the free end and propagates along the string. Considering that the speed of wave propagation in a string is given by v = sqrt(T/μ), where μ is the linear mass density of the string, and that the linear mass density is given by μ = m/L, where m is the mass of the string, describe the theoretical calculation process to determine the wave propagation speed on this guitar string. Then, relate this theoretical calculation to a practical experiment that could be performed in a laboratory to measure the wave speed on the string, considering that the masses and dimensions of the string are known. Discuss possible sources of error and how to minimize them in the experiment.
