MCQ

A sine wave is travelling in a medium. A particular particle has zero displacement at a certain instant. The particle closest to it having zero displacement is at a distance:

A
$\frac{\lambda}{4}$
B
$\frac{\lambda}{3}$
✓
$\frac{\lambda}{2}$
D
$\lambda.$

✓

Answer

Correct option: C.

$\frac{\lambda}{2}$

A sine wave has a maxima and a minima and the particle displacement has phase difference of $\pi$ radians. Therefore, applying similar argument we can say that if a particular particle has zero displacement at a certain instant. then the particle closest to it having zero displacement is at a distance is equal to $\frac{\lambda}{2}.$
