Waves that propagate through space and include light, radio, and X-rays, composed of oscillating electric and magnetic fields.

The orientation of oscillations in a light wave, which can be linear, circular, or elliptical.

The phenomenon that occurs when two or more waves overlap, resulting in a new wave pattern.

The bending of waves around obstacles or through openings, leading to the spreading of wave fronts.

A set of four fundamental equations that describe how electric and magnetic fields interact.

Complex numbers used to represent sinusoidal functions in terms of amplitude and phase.

A representation of a quantity that has a direction and magnitude at every point in space, used in physics.

A measure of the correlation between wave phases at different points in space or time, essential for interference patterns.

The amount of electric field passing through a surface area.

The electric flux through a closed surface equals the charge enclosed divided by the permittivity of free space.

The induced electromotive force in a circuit is equal to the rate of change of magnetic flux through that circuit.

The magnetic field circulation around a closed loop is related to the current encircled and electric displacement.

A surface representing points of a wave that are in the same phase of motion.

Light waves oscillate in a single plane.

The distance over which a coherent light source maintains a defined phase relationship.

Openings that allow light to pass through, affecting light's behavior.

Near-field diffraction pattern created when light passes through an aperture.

The permeability of free space, a constant used in electromagnetism, μ0 = 4π × 10^-7 Tm/A.

The permittivity of free space, a constant used in electromagnetism, ε0 = 8.85 × 10^-12 F/m.

A set of four fundamental equations that describe how electric and magnetic fields interact and propagate.

Indicates that a changing magnetic field induces an electric field, forming the basis for electromagnetic induction.

A modification of Ampere's Law which incorporates the displacement current, relating the magnetic field to electric current and displacement.

Describes the displacement of the wave, often represented as ψ(x, t) = A Sin[kx - ωt].

A shift in the wave's position along the x-axis, affecting where it starts.

Sine and cosine can represent the same wave with a phase shift; ψ can be A Cos(kx - ωt + ε).

The variable ψ represents the disturbance in the wave at given x and t.

A mathematical equation that describes wave behavior.
