A wire of uniform cross-section is stretched between two points 1m apart. The wire is fixed at oneend and n weight of 9 kg hung over a pulley at the other end produces fundamental frequency of 750Hz. What is the velocity oftrnnsverse waves propagating in the wire ? |

Answer» SOLUTION :In case of fundamental vibrations of STRING `(lambda//2) =L.i.e., lambda= 2xx1 =2M`.  Now as `v =f lambda and f = 750 Hz, V_T =2 xx 750 = 1500 m//s` i.e., `lambda=2m, f = 750 Hz and V_T =1500 m//s` |
