Two sinusoidal waves given below are superposed:
$y_1 = A \sin \left(kx - \omega t + \frac{\pi}{6}\right), \quad y_2 = A \sin \left(kx - \omega t - \frac{\pi}{6}\right)$
The equation of the resultant wave is:

  • A
    $y = \frac{A}{\sqrt{3}} \sin (kx - \omega t)$
  • B
    $y = A \sqrt{3} \sin (kx - \omega t)$
  • C
    $y = A \sqrt{3} \sin \left(kx - \omega t - \frac{\pi}{3}\right)$
  • D
    $y = \frac{A}{\sqrt{3}} \sin \left(kx - \omega t - \frac{\pi}{3}\right)$
