Wave equation. This equation describes the behaviour of waves such as sound waves,light waves and water waves. x represents a spatial variable,t is time,u is a scalar function,c is a fixed constant,the italic 'd' symbol is the partial derivative. The wave equation for a single dimension was formulated in 1746 by French mathematician Jean-Baptiste le Rond d'Alembert who was studying violin strings. The Swiss scientist Leonhard Euler in 1707 discovered the wave equation in a three space dimension | |
