Physics - Wave on String Question with Solution | TestHub

Equation of wave $y=5\sin \left(\frac{t}{0.04}-\frac{x}{4}\right)$ The standard equation of a wave in the given form is $y=a\sin \left(\omega t-\frac{2\pi x}{\lambda }\right)$ Comparing the given equation with the standard equation, we get $a=5\text{ and }\omega =\frac{1}{0.04}=25$ Therefore, maximum velocity of particles of the medium, $v_{\max }=a\omega =5\times 25=125{\mathrm{cms}}^{-1}=1.25{\mathrm{ms}}^{-1}$
