A Transverse Wave Is Traveling in the -X Direction on a String

Multiple Choice

A transverse wave is traveling in the -x direction on a string that has a linear density of 0.011 kg/m. The tension in the string is 7.4 N. The amplitude of the wave is 0.017 m; and its wavelength is 1.5 m. Which one of the following is the correct equation for the displacement of a particle from its equilibrium position?

A) y = (0.017 m) sin[(84 Hz) t + (4.2 m^-1) x]
B) y = (0.017 m) sin[(110 Hz) t + (4.2 m^-1) x]
C) y = (4.2 m) sin[(84 Hz) t + (59 m^-1) x]
D) y = (4.2 m) sin[(110 Hz) t - (59 m^-1) x]
E) y = (0.017 m) sin[(110 Hz) t - (8.4 m^-1) x]
