Thread: Equation for transverse wave View Single Post
 P: 5,462 The wave equation and the boundary conditions are separate matters. The simplest transverse wave equation is $$\frac{{{\partial ^2}y}}{{\partial {x^2}}} = {c^2}\frac{{{\partial ^2}y}}{{\partial {t^2}}}$$ You need to apply boundary conditions to establish the two arbitrary functions that appear in the solution.
