We can derive the wave equation, i.e., one-dimensional wave equation using Hooke's law. Consider the vital forces on a vibrating string proportional to the ...

In most cases, one can start from basic physical principles and from these derive partial differential equations (PDEs) that govern the waves. In Section 4.2 ...

The wave equation is a linear second-order partial differential equation which describes the propagation of oscillations at a fixed speed in some quantity.

Here we will derive the wave equation for homogeneous media, using the conservation of momentum (Newton's second law) and the conservation of mass.
