Linear Wave equation

  1. Sep 16, 2012 #1
    Hello,

    I am studying wave mechanics and I managed to derive the linear wave equation with a string. Now I don't understand the significance of the equation or why I can use a string oscillating to make it general and apply to all sorts of waves

    Edit:

    this one

    [tex] \frac{\partial^2 y}{\partial x^2}=\frac{1}{v^2} \frac{\partial^2 y}{\partial t^2}[/tex]

    What equation did you derive, can you post it.?

    This may help you understanding, where this equation comes from:
