SUMMARY
The discussion focuses on the calculation of theoretical wave speed using the formula vtheo. = √(F_T/μ), where F_T represents tension and μ is the linear mass density. It highlights the oversight of not including the mass of the string hanging over the pulley, specifically a 20cm string with a 100-gram mass. The participants analyze the impact of this omission on the accuracy of wave velocity calculations and explore the relationship between sound velocity and string length.
