Electromagnetic theory explores how energy travels through different media. It is generally divided into three main phenomena: Licensed by Google Electromagnetic Wave Propagation, Radiation, an...
: This describes how waves (like radio or light) travel through space or materials. It is governed by Maxwell’s equations, which define how the electric field ( E⃗modified cap E with right arrow above ) and magnetic field ( H⃗modified cap H with right arrow above The behavior of these waves is mathematically modeled

) oscillate perpendicular to each other and the direction of travel.
The behavior of these waves is mathematically modeled using the wave equation derived from Maxwell's equations:
