Bessel Function

Bessel functions are special mathematical functions that describe how waves or vibrations behave in circular or cylindrical systems, like ripples in a pond or sound waves in a tube. They arise as solutions to certain differential equations and help predict how these waves spread, oscillate, or diminish over distance. Bessel functions are fundamental in physics and engineering for modeling phenomena with circular symmetry, enabling precise calculations in areas such as acoustics, electromagnetism, and signal processing.
