Electromagnetic Wave Propagation in Air
Electromagnetic waves are a form of energy that can travel through space and matter. They are composed of oscillating electric and magnetic fields that are perpendicular to each other and to the direction of propagation. In air, electromagnetic waves can propagate over long distances with minimal attenuation.
The propagation of electromagnetic waves in air is affected by several factors, including frequency, polarization, and distance. Higher frequency waves are more susceptible to attenuation than lower frequency waves. The polarization of the wave also affects its propagation, with vertically polarized waves experiencing less attenuation than horizontally polarized waves.
