Question 8

A periodic travelling wave 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. Figure B shows the displacement of the particle at X = 0 as a function of time. The particle positions are measured from the left end of the string (X = 0) and the wave pulses move to the right.
