A string with one end fixed as U(x=0,t)=0. The other end is attached to a massless ring which moves frictionlessly along a rod at x=L
a) Explain the boundary condition at x=L should be d/dx U(x,t) = 0.
b) Find the normal modes for the wave equation d2/dt2 U(x,t) = c2 * d2/dx2 U(x,t) with the above boundary conditions.
c) Plot the three lowest frequency normal modes.
