MCQ
A sine wave of wavelength $\lambda $ is travelling in a medium. The minimum distance between the two particles, always having same speed, is
  • A
    $\frac{\lambda }{4}$
  • B
    $\frac{\lambda }{3}$
  • ✓
    $\frac{\lambda }{2}$
  • D
    $\lambda $
✓

Answer

Correct option: C.
$\frac{\lambda }{2}$
c
In a sine wave particles that are separated by a distance of odd multiple of half the wave length move with same speed and but in opposite direction. The minimum separation is $\frac{\lambda}{2}$
