Physics - Wave on String Question with Solution | TestHub

In a medium, the phase difference between two particles separated by a distance $x$ is ${\left(\frac{\pi }{5}\right)}^{\circ }$. If the frequency of the oscillation of particles is $25\mathrm{Hz}$ and the velocity of propagation of the wave is $75\mathrm{m}/\mathrm{s}$, then the value of $x$ is
