Three-Dimensional Wave Equation

Three-Dimensional Wave Equation

The three-dimensional wave equation is given by:

\[ \frac{\partial^2 u}{\partial t^2} = c^2 \left( \frac{\partial^2 u}{\partial x^2} + \frac{\partial^2 u}{\partial y^2} + \frac{\partial^2 u}{\partial z^2} \right) \]

General Solution

The general solution is given by:

\[ u(x, y, z, t) = F(x, y, z) \cdot G(t) \]

Here, \(F(x, y, z)\) represents the spatial part of the solution, and \(G(t)\) represents the temporal part.

It's important to note that the specific form of the solution depends on the nature of the wave and the given conditions. If you have a specific problem or set of conditions in mind, providing more details would allow for a more tailored explanation.

For a simple harmonic wave, the solution might involve sine and cosine functions. The solution process often requires advanced mathematical techniques such as separation of variables, Fourier series, or Fourier transforms, depending on the complexity of the problem.
