james clerk maxwell
an electromagnetic wave consists of two waves that are oscillations of the electric and magnetic fields. an electromagnetic wave travels in a direction that is at right angles to the oscillation direction of both fields. in the 19th century, james clerk maxwell showed that, in vacuum, the electric and magnetic fields satisfy the wave equation both with speed equal to that of the speed of light. from this emerged the idea that light is an electromagnetic wave. electromagnetic waves can have different frequencies (and thus wavelengths), giving rise to various types of radiation such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays.

inhomogeneous electromagnetic wave equation









































in electromagnetism and applications, an inhomogeneous electromagnetic wave equation, or nonhomogeneous electromagnetic wave equation, is one of a set of wave equations describing the propagation of electromagnetic waves generated by nonzero source charges and currents. the source terms in the wave equations makes the partial differential equations "inhomogeneous", if the source terms are zero the equations reduce to the homogeneous electromagnetic wave equations. the equations follow from maxwell's equations.
