Two transverse waves travel along the same taut string and interfere. Waves 1 and 2 are described, respectively, by the function y1(x, t) = A sin(kx - ωt) and y2(x, t) = A cos(3kx + 3ωt). The phases (arguments of the sine and cosine functions) are in radians, as usual, and A = 7.9 cm, k = 5.1 rad/m, ω = 3.2 rad/s. a. In what direction does each wave travel?  Wave 1 travels in the negative x-direction, while wave 2 travels in the positive x-direction. There is not enough information. Wave 1 travels in the positive x-direction, while wave 2 travels in the negative x-direction. Because wave 2 is described using a cosine, it does not travel. Wave 1 travels in the negative x-direction. Because wave 1 is described using a sine, it does not travel. Wave 2 travels in the negative x-direction. Both waves travel in the positive x-direction. Both waves travel in the negative x-direction. b.  Which option correctly describes wave 2 as a sine wave? There…
