Key Concepts

Electromagnetic Waves

Electromagnetic waves consist of oscillating electric and magnetic fields that propagate through space. They are solutions to Maxwell's equations and travel at a constant speed in vacuum, where the fields are perpendicular to one another as well as to the direction of travel.

Relationship between Electric and Magnetic Field Amplitudes

In free space, the amplitudes of the electric and magnetic fields in an electromagnetic wave are linked by the speed of light. This relationship is described by the equation E = cB, where E is the electric field amplitude, B is the magnetic field amplitude, and c is the speed of light. This proportionality ensures that the energy in the wave is correctly apportioned between the electric and magnetic components.

Speed of Light

The speed of light is a fundamental constant (approximately 3 x 10^8 m/s in vacuum) that plays a crucial role in electromagnetic theory. It not only defines the propagation speed of electromagnetic waves but also appears in the relation between the amplitudes of the electric and magnetic fields.
