ELECTROMAGNETIC WAVES IN A CONDUCTING MEDIUM
Electromagnetic Waves in a Conducting Medium: There may be conduction current in the medium but the charge density is zero everywhere.

Propagation of Electromagnetic Waves in Dielectric Medium

PROPAGATION OF ELECTROMAGNETIC WAVES IN DIELECTRIC MEDIUM

1) In Dielectric Medium there is no Charge Carrier so Current Density will be zero.
2) If Dielectric Medium is Isotropic then Volume Density will be zero.

Fundamental of Electromagnetic, Fundamental of EM Waves

FUNDAMENTAL OF ELECTROMAGNETIC

PROPERTIES OF ELECTROMAGNETIC WAVES
1) Electromagnetic wave propagates.
2) In Vacuum Electromagnetic Wave moves with velocity.
3) Electromagnetic waves of different frequencies can exist. All such wave propagates with speed c.
4) No material particle moves with electromagnetic waves.
5) Electric field vector plays role of light vector.
