A sinusoidal wave moving along a string is shown twice in the figure, as crest A travels in the positive direction of an x axis by distance d = 6.20 cm in 4.10 ms. The tick marks along the axis are separated by 13.0 cm; height H = 6.00 mm. If the wave equation is of the form y(x, t) = ym sin(kx ± ωt ), what is the value of ω?
