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 the gure, as the antinode A travels from an extreme upward displacement to an extreme downward displacement in 6.04 ms. The tick marks along the axis are separated by 11.0 cm; height H is 1.80 cm. Let the equations for one of the two waves be of the form ylx, t) = ym sin(l
