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.

A. What is the wavelength of the wave?	Answer
B. What is the minimum time required for the particles to return to their respective positions at t = 0?	Answer
C. What is the amplitude of the wave?	Answer
D. Determine the speed of the wave.	Answer
E. What is the tension in the string?	Answer
