A standing wave is established on a string of length L=0.60 mL = 0.60 \text{ m} fixed at both ends. The wave speed is v=240 m/sv = 240 \text{ m/s}. When the string vibrates in its third harmonic, what is the minimum time required for a particle initially at rest at an antinode to return to rest at the same position?
