Three Sinusoidal Waves Three sinusoidal waves of the same frequency travel along a string in the positive direction of an $x$ axis. Their amplitudes are $y_{1}, y_{1} / 2$, and $y_{1} / 3$, and their initial phases are $0, \pi / 2$, and $\pi \mathrm{rad}$, respectively. What are (a) the amplitude and (b) the phase constant of the resultant wave? (c) Plot the wave form of the resultant wave at $t=0.00 \mathrm{~s}$, and discuss its behavior as $t$ increases.
