Maxwell’s Equations And Electromagnetic Waves
Ampere’s law with Maxwell’s addition:
- Describes the relationship between a changing electric field and the generation of a magnetic field.
Faraday’s law of electromagnetic induction:
- Explains how a changing magnetic field can induce an electric field.
The displacement current and Maxwell’s fourth equation:
- Introduces the concept of displacement current to account for the continuity of current flow in the presence of dielectrics.
Electromagnetic waves:
- Describes the propagation of combined electric and magnetic fields through space.
Properties of electromagnetic waves: speed, wavelength, frequency:
- Relates the speed of light to the wavelength and frequency of electromagnetic waves.
Wave equation for electromagnetic waves:
- Describes the mathematical relationship between the electric and magnetic fields of an electromagnetic wave.
Transverse nature of electromagnetic waves:
- Explains that the electric and magnetic fields of an electromagnetic wave are perpendicular to the direction of propagation.
Polarization of electromagnetic waves:
- Describes the orientation of the electric field of an electromagnetic wave.
Energy and momentum of electromagnetic waves:
- Relates the energy and momentum carried by electromagnetic waves to their electric and magnetic fields.
