Electromagnetic wave equation - Wikipedia
WebThe electromagnetic wave equation is a second-order partial differential equation that describes the propagation of electromagnetic waves through a medium or in a vacuum. It is a three-dimensional form of the wave equation. The homogeneous form of the equation, written in terms of either the electric field E or the magnetic field B, takes the form: Webthe vacuum are related by ω =c k~ . This relation implies that electromagnetic waves are disper-sionless with velocity c: the speed of light. In materials, like a prism, light can have … bissell cleaning chemicals
