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

question 28

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]
