Homework Statement
An oscillator is attached to one end of a horizontal string. The other end passes over a frictionless pulley and is held taught by a mass m. The distance between the oscillator and the pulley is 1.2m. The string has a linear mass density of 1.6g/m and the frequency of the oscillator is 120Hz. What must be m mass is the string is to oscillate in its fourth harmonic?
Be sure to draw a useful well labelled picture and sketch the standing wave pattern, and prove the units work.
