Résumé:
The aim of this memory is to study some physical problems
related to wave equations.
These wave phenomena appear in numerous applications such
as: sound waves and electromagnetic waves...
In the first chapter, we recalled some definitions and
properties of PDEs, as well as some generalities that we used
in the following chapters.
The second chapter was devoted to solving the wave equation,
where we presented three methods of resolution, namely the
D'Alembert method, the Fourier method and the Kirchhoff
method.
Finally, and through the last chapter, we have proposed a
numerical solution of the equation in question via the finite
difference method.
