The speed of a wave in a string is given by v = sqrt (FT/m), where FT is the tension in the string and m = mass / length of the string.
A 2.00 m long string has a mass of 28.50 g. A 1024 g mass is attached to the string and hung over a pulley (see illustration from one of the team problems). The end of the string is then vibrated at a frequency of 134 Hz. Find the wavelength for the wave generated. Give your answer in centimeters (cm) and with 3 significant figures.
