A Periodic Traveling Wave Is Generated on a String of Linear

question 54

Multiple Choice

A periodic traveling wave is generated on a string of linear density 8.0 × 10-4 kg/m. Figure A shows the displacements of the particles in the string as a function of the position x along the string at t = 0 s. Figure B shows the displacement of the particle at x = 0 m as a function of time. The particle positions are measured from the left end of the string (x = 0 m) and the wave pulses move to the right.
-Determine the speed of the wave.

• A)0.01 m/s
• B)0.02 m/s
• C)0.03 m/s
• D)0.04 m/s
• E)0.05 m/s
