534 Superposition and Standing Waves *P18.24 For the whole string vibrating, d NN == 064 2 . m λ ; = 128 m . The speed of a pulse on the string is vf s = 330 1 422 m m s . (a) When the string is stopped at the fret, d NN 2 3 2 m ; = 0853 m f v = 422 495 ms m Hz . . FIG. P18.24(a) (b) The light touch at a point one third of the way along the string damps out vibration in the two lowest vibration states of the string as a whole. The whole string vibrates in its third resonance possibility: 30 6 4 3 2 d NN m ; = 0427 m f v = 422 990 Hz m . . FIG. P18.24(b) P18.25 f v L 1 2 = , where v T = F H G I K J µ 12 (a) If L is doubled, then fL 1 1 will be reduced by a factor 1 2 . (b) If is doubled, then f 1 will be reduced by a factor
