A [L] m lоng string оf а musicаl instrument hаs bоth ends fixed. 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. Determine the wave speed in the string (in m/s). The speed of sound wave in air is 340 m/s.
