A sinusoidal transverse wave traveling in the positive direction of an x axis has an amplitude of 1.0 cm, a wavelength of 19 cm, and a frequency of 390 Hz. If the wave equation is of the form y(x,t) = ym sinlkx - wt), what are (a) ym, (b) k, and (c) w, (d) the correct choice of sign in front of to? What are (e) the maximum speed of a point on the cord and (f) the speed of the wave? (a) Number n Units v (b) Number Units V (c) Number n Units v (d) V (e) Number n Units V (f) Number n Units V
