Sinusoidal Plane-wave Solutions of The Electromagnetic Wave Equation - Plane Waves

Plane Waves

The plane sinusoidal solution for an electromagnetic wave traveling in the z direction is (cgs units and SI units)

for the electric field and

for the magnetic field, where k is the wavenumber,

is the angular frequency of the wave, and is the speed of light. The hats on the vectors indicate unit vectors in the x, y, and z directions.

The plane wave is parameterized by the amplitudes

and phases

where

Famous quotes containing the words plane and/or waves:

    As for the dispute about solitude and society, any comparison is impertinent. It is an idling down on the plane at the base of a mountain, instead of climbing steadily to its top.
    Henry David Thoreau (1817–1862)

    And the waves sing because they are moving.
    And the waves sing above a cemetery of waters.
    Philip Larkin (1922–1986)
