(c) Since f = 120 Hz, ω = 2 π f = 754 rad/s 2 7.5 10 rad/s. ≈× (d) The sign in front of is minus since the waves are traveling in the + x direction. The results may be summarized as y = (3.0 mm) sin[(31.4 m 1 ) x – (754 s 1 ) t ]] (this applies to each wave when they are in phase). 68. We use Eq. 16-52 in interpreting the figure. (a) Since y = 6.0 mm when φ = 0, then Eq. 16-52 can be used to determine
