A sonometer wire 100 cm long has a fundamental frequency of 330 Hz . The velocity of propagation of transverse waves on the wire is

Options

A. A)`330ms^(-1)`
B. B)`660ms^(-1)`
C. C)`990ms^(-1)`
D. D)`115ms^(-1)`

Answer

B

Explanation

`n=(v)/(lambda)=(v)/(2l)`
`thereforev=n(2l)=330xx2=660ms^(-1)`
