Question

The figures represent two snaps of a travelling wave on a string of mass per unit length, mu = 0.25 kg/m. The two snaps are taken at time t = 0 and at t equals fraction numerator 1 over denominator 24 end fractions. Then

Figure I

Figure II

  1. speed of wave is 4 m/s    
  2. the tension in the string is 4 N    
  3. the equation of the wave is y = 10 sin (pix – 4pt plus fraction numerator pi over denominator 6 end fraction)    
  4. the maximum velocity of the particle equals fraction numerator pi over denominator 25 end fraction m divided by s    

The correct answer is: speed of wave is 4 m/s
