71. (a) The amplitude is y m = 1.00 cm = 0.0100 m, as given in the problem. (b) Since the frequency is f = 550 Hz, the angular frequency is ω = 2 π f = 3.46 × 10 3 rad/s. (c) The angular wave number is 3 / (3.46 10 rad/s)/(330 m/s) 10.5 rad/m kv == × = . (d) Since the wave is traveling in the – x direction, the sign in front of is plus and the
