Vedclass · Answer

(B) To determine the direction of the velocity of particles in a wave,we can use the rule: if the wave travels from right to left,the wave profile shifts to the left after a small time interval $\Delta t$. By shifting the wave slightly to the left,we can observe the displacement of each particle: $1$. Particles at $A, B$ are moving upwards. $2$. Particle at $C$ is at the crest,so its velocity is zero. $3$. Particles at $D, E, F$ are moving downwards. $4$. Particle at $G$ is at the trough,so its velocity is zero. $5$. Particle at $H$ is moving upwards. Comparing this with the given options,the particles at $D, E$ and $F$ have downward velocity. Thus,option $B$ is correct.

$A$ transverse wave is travelling along a stretched string from right to left. The figure shown represents the shape of the string at a given instant. At this instant,
