A string is attached between two rigids walls that are positioned L = 2.00 meters apart. The string is set into motion so that it exhibits the standing wave pattern shown in the figure. The frequency of oscillation of the string in this standing wave mode is 5.0 Hz. Calculate the wave speed for waves on this string. 8.00 m/s 16.0 m/s 2.00 m/s 4.00 m/s 1.00 m/s
