The overall stretched length of the band is 23.11 cm. One side of the band is plucked, setting up a vibration in 8.257 cm of the band's stretched length. What is the lowest frequency of vibration that can be set up on this part of the rubber band? Assume that the band stretches uniformly. 94.00 Hz Submit Answer Incorrect.
