A string of length L and linear density 3.2 g/m is under a tension T=18 N. It is connected to an oscillator that is oscillating at a constant frequency of 50 Hz. The amplitudes of the oscillations at the two ends of the string are very small so that nodes can be assumed to exist there. Calculate the shortest possible value of the length L that allow the setup of a standing wave on the string, with a node at the midpoint of the string.
