Using the wave equation in research on the physical process

Many natural and social sciences can not do without mathematics. In particular, in physics, the various laws of mechanics and hydrostatics were discovered only by simple observation. But modern physics requires a good mathematical apparatus, since some of them can not be done with simple arithmetic operations. Currently, most of them compute with the help of powerful computers. To describe physical processes in mathematics and mathematical physics. For example, the wave equation is used in many cases of physics. Its particular solution gives an accurate description of the wave processes and allows us to determine the state of the system at any time.
