Vedclass · Answer

(B) Given: Length of the string $\ell = 1\,m$,Frequency $f = 300\,Hz$,Number of segments $n = 3$.For a string fixed at both ends vibrating in $n$ segments,the length of the string is given by $\ell = n \frac{\lambda}{2}$.Substituting the values,$1 = 3 	imes \frac{\lambda}{2}$,which gives the wavelength $\lambda = \frac{2}{3}\,m$.The speed of the transverse wave $v$ is given by the relation $v = f \lambda$.Substituting the values,$v = 300 	imes \frac{2}{3} = 200\,m/s$.

$A$ string $1\,m$ long is driven by a $300\,Hz$ vibrator attached to its end. The string vibrates in $3$ segments. The speed of transverse waves in the string is equal to .... $m/s$.
