Physics - Wave on String Question with Solution | TestHub

In a transverse wave the particles of the medium vibrate about their mean positions in a direction perpendicular to the direction of wave propagation.
Here, the particle velocity is given by $\frac{dy}{dt}$ and wave velocity is given by $\frac{dx}{dt}$. Hence, the angle between particle velocity and wave velocity in a transverse wave is $\frac{\pi }{2}$.
