Two sinusoidal waves with the same amplitude of 6.00 mm and the same wavelength travel together along a string that is stretched along an x axis. Their resultant wave is shown twice in Fig. 16 39. as velley travels in the negative direction of the x axis by distance d= 56.0 cm in 8.0 ms. The lick matks along the axis are separated by 10cm, and height H is 8.0mm. Let the equation for one wive be of the form y(x,t) =y_m sin (kx pm omegat+phi_(1))," where "phi_(1)=0and you must choose the correct sign in front of omega. For the equation for the other wave, what are (a) y_(m), (b) k, (c) omega, (d) phi_(2), and (e) the sign in front of omega?
