How radio frequency works

By Andrew Joseph     November 28, 2020     How stuffs work, Physics     No comments   

 


Radio waves are electromagnetic waves that include light, microwaves, x-rays, infrared, ultraviolet, etc. Radio waves are composed of both electric fields and magnetic fields. In fact, a wave is produced when a time-changing electric field induces a time-changing magnetic field and then the time-changing magnetic field induces another time-changing electric field and the process repeats. This is all described by a set of equations modified and assembled by James Clerk Maxwell, so today they are called Maxwell’s equations.
