Thank you Ken G!

Thanks for your reply! I will read carefully your answer. I'll change my question, When the pulse struck the massless ring on the free end, the ring will go up and then back to y=0 and reflect the pulse without change of sign. Is it true that the ring will go up as high as 2*y ( twice the...

From Halliday Resnick, Fundamentals of Physics 8E. That should explain why they are comparable.

sorry, a = d2y/dt2 = v*(dv/dx) should be 'x' instead of 'y' So, a = d2x/dt2 = v*(dv/dx). d(dx/dt)/dt = dv/dt = dv/dx * dx/dt = dv/dx * v.

a = d2y/dt2 = v*(dv/dx) Also you have kx + ma = 0, then substitute a with v*(dv/dx), then solve the first ODE.

1. Why do waves propagates on a string? I mean, when we create a disturbance on one end, it affects all the string. How can it be? 2. How can there be a continuous flow of energy along a medium when the particles of the medium simply oscillate about their equilibrium positions? 3 Intuitively...
