57.If a string is 1.6 meters long and it vibrates in the first and second harmonics, determine the wavelength for each pattern. 58.A string is 2.4 meters long and vibrates as the first harmonic. The string vibrates up and down with 30 complete vibrational cycles in 5 seconds. Determine the frequency, period, wavelength and speed for this wave. Show your work. 59.A string is 12.0 cm long and vibrates as the third harmonic. The string vibrates up and down with 50 complete vibrational cycles in 10 seconds. Determine the frequency, period, wavelength and speed for this wave.
