Electromagnetic Field Theory
As a result of reflection from a plane conducting wall, electromagnetic waves acquire an apparent velocity greater than the velocity of light in space. This is called the
Gauss’s law states that total electric flux through any surface is equal to the total charge enclosed by surface.
Gauss’s static that divergence of D = ρu.
An electric flux line is an imaginary path or a line drawn in such a way, that its direction at any point is the direction of electric field at that point.
For a uniform long charged line with l1 c/m the electric field intensity E is given as E = ρL/(π ε0.r).
