According to Maxwell's Equations electromagnetic waves are able to propagate without the need for any medium: moving electric charges induce a moving magnetic field, a moving magnetic field induces moving electric charges, ad infinitum...
radio waves are propagated through the interaction of
Electromagnetic waves.
Electromagnetic waves (those that can transmit their energy through a vacuum) have both an electric and a magnetic component. They are created by a vibration of charged particles. When passing through a medium, they are propagated by absorption and reemission of the wave energy by the atoms in the material.
Wave
EM waves stand for Electromagnetic waves.
EM waves or electromagnetic waves is radiant energy.
EM waves stand for Electromagnetic waves.
EM waves are both Transverse and Longitudinal.
In the form of longitudinal waves
mechanical waves need a medium to travel through, electromagnetic waves do not. Electromagnetic waves can travel through space, mechanical waves can not.:PElectromagnetic waves do not require a medium, but mechanical waves do.
Radio waves
Electromagnetic waves have no odor.
