Wondered Why we studied Bessel Function? Here is the answer.

Bessel’s Function is basically the solution to Laplace’s Equation in Cylindrical Form and solution to Helmholtz’s equation in spherical form.Bessel functions are therefore especially important for many problems of wave propagation and static potentials. Bessel’s Function find its importance in Electromagnetic wave propagation in cylindrical wave guides. It is also important for Signal Processing(e.g. in Bessel Filter, FM synthesis).
