(B) The standard wave equation is given by $Y = A \sin(\omega t - kx)$.Comparing this with the given equation $Y = 5 \sin(10\pi t - 0.1\pi x)$,we get the wave number $k = 0.1\pi \ rad/m$.The phase difference $\Delta\phi$ between two points separated by a distance $\Delta x$ is given by the formula $\Delta\phi = k \cdot \Delta x$.Given $\Delta x = 10 \ m$ and $k = 0.1\pi \ rad/m$,we have:$\Delta\phi = (0.1\pi) 	imes 10 = \pi \ rad$.Therefore,the phase difference is $\pi$.

The equation of a wave is given by (all quantities expressed in $M.K.S.$ units) $Y = 5 \sin(10\pi t - 0.1\pi x)$ along the $x$-axis. The phase difference between two points separated by a distance of $10 \ m$ along the $x$-axis is:
