Answer» Adjoining figure shows the snapshot of two waves A and B at any time t. The equation for A is $y = A s i n (k x - ω t - ϕ)$ , and for B it is y = A sin $(k x - ω t)$ . It is clearly shown in the figure that wave A is ahead of B by a distance $\frac{ϕ}{k}$ . The motion of a single point in time, i.e., y versus t for two waves is best represented by
