Vedclass · Answer

(C, D) For a wave traveling in the negative $x$-direction, the velocity of a particle at any point $x$ is given by $v_p = -v \cdot (	ext{slope})$, where $v$ is the wave speed and the slope is $\frac{\partial y}{\partial x}$.Since the wave is moving in the negative $x$-direction, $v$ is negative. Thus, $v_p = |v| \cdot (	ext{slope})$.Therefore, a particle moves downwards $(v_p Looking at the graph:- At point $a$, the slope is positive, so it moves upwards.- At point $b$, the slope is zero (it is a crest).- At point $c$, the slope is negative, so it moves downwards.- At point $d$, the slope is negative, so it moves downwards.- At point $e$, the slope is positive, so it moves upwards.- At point $f$, the slope is zero (it is a trough).- At point $g$, the slope is positive, so it moves upwards.- At point $h$, the slope is positive, so it moves upwards.Thus, points $c$ and $d$ are moving downwards.
