Q. A sonometer wire 100 cm long has a fundamental frequency of 330 Hz. The velocity of propagation of transverse waves on the wire is
A) 330 $ms^{- 1}$
B) 660 $ms^{- 1}$
C) $990\ ms^{- 1}$
D) $115\ ms^{- 1}$
Explanation
(b) Frequency
$n = \frac{v}{\lambda} = \frac{v}{2\iota}$
$\therefore\ v = n(2\iota) = 330 \times 2 = 660\ ms^{- 1}$
