Physics - Wave on String Question with Solution | TestHub

Given, frequency$f= 500 \mathrm{Hz}$, velocity$v = 350 \mathrm{m} {\mathrm{s}}^{-1}$, phase$\varphi =60^{\circ }$

By the formula,$\lambda =\frac{v}{f}=\frac{350}{500}=\text{0.7 m}$

Also we know that$\Delta \text{x}=\Delta \varphi \frac{\lambda }{2\pi }$

$=60\times \frac{\pi }{180}\times \frac{\text{0.7}}{2\pi }$

$\approx \text{0.12 metre}\approx \text{12 cm}$
