Composite String Question

  • #1

Homework Statement


The composite string consists of two strings having lengths of l1 and l2, and linear densities [tex]\rho[/tex]1 and [tex]\rho[/tex]2

Find y[tex]_{r}[/tex] / y[tex]_{i}[/tex] in terms of l1 and l2, and [tex]\rho[/tex]1 and [tex]\rho[/tex]2

Homework Equations


y[tex]_{r}[/tex] is the wave reflected from the "interface" of the two strings, and y[tex]_{i}[/tex] is the incident wave from the left of the string with length l1 and linear density [tex]\rho[/tex]1


The Attempt at a Solution


actually, i dont know. my professor provided me only with the string wave function, y=yosin(kx-[tex]\omega[/tex]t), which obviously has no mention of linear densities.

Help please. any suggestion would be appreciated. Thanks ^_^
