How does the presence of a conducting medium affect the propagation of electromagnetic waves, according to Maxwell's equations?
How does the presence of a conducting medium affect the propagation of electromagnetic waves, according to Maxwell's equations?
- It causes the waves to propagate faster than in free space due to reduced impedance.
- It converts transverse waves into longitudinal waves.
- It has no effect on the wave propagation, as electromagnetic waves are independent of the medium.
- It leads to attenuation of the waves as energy is dissipated due to the medium's conductivity. (correct)
