Q. In sine wave, minimum distance between 2 particles always having same speed is
A) $\frac{\lambda}{2}$
B) $\frac{\lambda}{4}$
C) $\frac{\lambda}{3}$
D) $\lambda$
Explanation
(a) Since wave
Particle velocity
$v_{p} = \frac{dy}{dt} = slope\ of\ wave$

At that point. As slope at A and B is zero. Hence, the velocity at A and B will be same. Distance between A and B is
$\frac{\lambda}{2}$
