Question
Here given graph shows the motion of particle at x =$\frac{\lambda}{2}$of a progressive wave. Then the equation of the wave if wave is going in +ve x-direction and if wave is going in –ve x-direction will be respectively.$\left( Here,T = \frac{2\pi}{\omega} \right)$
Options
A.y = A sin$\left( \omega t - kx + \frac{\pi}{4} \right)$, y = A sin$\left( \omega t + kx + \frac{\pi}{4} \right)$
B.y = A sin$\left( \omega t - kx + \frac{3\pi}{4} \right)$, y = A sin (ωt + kx)
C.y = A sin$\left( \omega t - kx + \frac{9\pi}{4} \right)$, y = A sin (ωt + kx)
D.y = A cos$\left( \omega t - kx + \frac{\pi}{4} \right)$, y = A cos$\left( \omega t + kx + \frac{\pi}{4} \right)$
