Question

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

Options

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)


The correct answer is C.
