Question

Why does boundary condition hold in electromagnetic waves?

Answer 1

Answer: When an electromagnetic field faces an abrupt change in the The perittivity. And permeability, certain conditions on electric and magnetic fields on the interface are to be respected for the continuity

Answer 2

When an electromagnetic field faces an abrupt change in the permittivity. and permeability, certain conditions on electric and magnetic fields on the. interface are to be respected for the continuity. These conditions of continuity. are known as the boundary conditions for the electromagnetic field.

The speed of the em-waves in a vacuum is determined by the ratio of the peak value of electric and magnetic fields. Drive the expression for electric field at a point on the equatorial line of an electric dipole.
