Question
Consider a setup of a string where one is end attached to a vibrator of fixed frequency f while the other end of the string passes over a pulley and has a mass m hanging off of it. There is a distance L between the string’s points of contacts with the vibrator and the pulley, and you can consider these points of contact to be fixed. Given that the string forms a standing wave in the fourth harmonic along the length L , derive an equation for the linear mass density μ of the string in terms of the given parameters f, m, L, and any other known constants.
I am not sure of how to set up this equation.
