MCQ
In the standing wave shown, particles at the positions $A$ and $B$ have a phase difference of
  • A
    $0$
  • B
    $\frac{\pi}{2}$
  • C
    $\frac{5 \pi}{6}$
  • $\pi$

Answer

Correct option: D.
$\pi$
d
(d)

Let, $y_A=A \sin \omega t$

$y_A=A \sin \omega t+\phi$

To convert $\sin \theta$ to $-\sin \theta, \phi$ must be $\pi$. Hence phase difference between is $\pi$.
