Vedclass · Answer

(B) To determine the direction of velocity of particles in a transverse wave,we can visualize the wave moving slightly in the direction of propagation.Since the wave is moving from right to left,the wave profile shifts to the left.$1$. At point $D, E, F$: As the wave moves to the left,the profile at these points will shift downwards,meaning these particles have a downward velocity.$2$. At point $C, G$: These are extreme positions (crests and troughs),so their instantaneous velocity is zero.$3$. At point $A, B, H$: As the wave moves to the left,the profile at these points will shift upwards,meaning these particles have an upward velocity.Therefore,the particles at $D, E$ and $F$ have downward velocity. The correct option is $B$.
