The wave equation is a linear hyperbolic differential equation in partial derivatives specifies the small transverse vibrations of thin membranes or strings and other oscillatory processes in continuous media (acoustic, mostly linear: sound in gases, liquids and solids) and electromagnetism (electrodynamics). Finds application in other fields of theoretical physics, for example in the description of gravitational waves. Is one of the basic equations of mathematical physics.

Уравнения в частнo‘х производнo‘х дифференциалнo‘м уравнением с частнo‘ми производнo‘ми назo‘вается уравнение, связo‘ваюhее независимo‘е переменнo‘е, искомую функцию многих переменнo‘х и ее частнo‘е производнo‘е. Порядком уравнения с частнo‘ми производнo‘ми назo‘вается порядок наивo‘сшей производной входяhей в это уравнение. Дифференциалное уравнение с частнo‘ми производнo‘ми назo‘вается линейнo‘м, если искомая функция и ее частнo‘е производнo‘е входят в него линейно (т.е. в первой степени).
Partial differential equations differential equation with partial derivatives is called the equation linking the independent variables, desired function of many variables and its partial derivatives. The order of equations is called the order of the highest derivative included in the equation. Differential equation with partial derivatives is called linear, if the target function and its partial derivatives enter it linearly (i.e., first degree).
