SUMMARY
The discussion centers on the relationship between mass and wave speed on a vertical wire. When a mass M hangs from a wire of length L, the wave speed V is determined by the formula v = √(T/μ), where T is the tension and μ is the mass per unit length. Doubling the mass M increases the tension in the wire, which affects the wave speed. The correct answer for the new wave speed, after doubling the mass, is √2 times the original speed V, not simply √2.
