일반물리학 1 — Waves-I: Problem 29

29 In Fig. 16-31, a sinusoidal wave moving along a string is shown twice as crest A travels in the positive direction of an x axis by distance \(d = 6.0\text{ cm}\) in \(3.0\text{ ms}\). The tick marks along the axis are separated by \(10\text{ cm}\); height \(H = 6.00\text{ mm}\). The equation for the wave is in the form \(y(x, t) = y_m \sin(kx \pm \omega t)\), so what are (a) \(y_m\), (b) \(k\), (c) \(\omega\), and (d) the correct choice of sign in front of \(\omega\)?
