Two sinusoidal waves with the same amplitude and wavelength travel through each other along a string that is stretched along an x axis. Their resultant wave is shown twice in Figure as the anti node A travels from an extreme upward displacement to an extreme downward displacement in 6.0ms. The tick marks along the axis are separated by 10cm; height H is 1.80 cm. Let the equation for one of the two waves be of the form y(x, t) = ym sin (kx + wt).In the equation for the other wave, what are(a) ym(b) k,(c) w, and(d) The sign in front ofw?
