A [L] m lоng string оf а musicаl instrument hаs a mass оf [m] kg. When the string resonates, it forms a standing wave. The figure shows a snapshot of the standing wave at t = 0. The resulting sound wave in the surrounding air has a wavelength of [lamda] m. Calculate the tension in the string (in Newtons) required to sustain this vibration. The speed of sound wave in air is 340 m/s.
