A transverse wave is travelling on a string with velocity 'V'. The extension in the string is ' $x^{'}$ . If the string is extended by $50%$ , the speed of the wave along the string will be nearly (Hooke's law is obeyed)

Options:

Answer:

Solution:

Speed of sound $V = \frac{T}{μ}$ $V \propto T$ So $\frac{V _{2}}{V _{1}} = \frac{1.5 x}{x}$ So $T \propto x$
