A wave has an amplitude equal to 4.0m, angular speed \(\frac{1}{3} \pi\) rads^-1 and phase angle \(\frac{2}{3} \pi\) rad. The displacement y of the wave particle is given as

• A.y = 4 sin \(\frac{\pi}{3}\)(t + 2)
• B.y = 4 sin \(\frac{\pi}{3}\)(t + \(\frac{2}{\pi}\)
• C.y = 4 sin \(\frac{\pi}{3} (2t + 1)\)
• D.y = 4 sin \(\frac{\pi}{3} (t + 2)
